Casey at the Bat.

Sen. Obama picks up a Pennsylania superdelegate in Senator Bob Casey, who had previously pledged to stay neutral. “Obama strategists hope that Casey can help their candidate make inroads with the white working-class men who are often referred to as “Casey Democrats.” This group identifies with the brand of politics Casey and his late father, a former governor, practiced — liberal on economic issues but supportive of gun rights and opposed to abortion.

Clinton donors: Our money, our rules.

“We have been strong supporters of the DCCC. We therefore urge you to clarify your position on super-delegates and reflect in your comments a more open view to the optional independent actions of each of the delegates at the National Convention in August.” My, that’s classy. A group of twenty top Clinton fundraisers (among them Robert Johnson, of BET, drug hysteria, and estate tax fame) attempt to blackmail Speaker Pelosi into backing the Senator’s convention coup…or else!

Uh, did they not hear about Obama’s $55 million haul, overwhelmingly from small donors, last month, or the $32 million he made in January? Welcome to the 21st century, y’all: Fatcat donors who think their money trumps the will of voters have gone the way of Betamax, HD-DVD, Pets.com, and the landline. But, way to embarrass yourselves, and your candidate, by wildly overstating the importance of your lucre. Honestly, you might as well take your checks over to the GOP — I’m sure your credit’s good with them.

More cracks in the wall. | Mark the date.

“‘If we have a candidate who has the most delegates and the most states,’ the Democratic party should come together around that candidate, Cantwell said. The pledged delegate count will be the most important factor, she said, because that is the basis of the nominating process.” Senator and Clinton superdelegate Maria Cantwell (D-WA) says she’ll vote for the pledged delegate leader in the end, meaning — barring a political meltdown of historic proportions — Sen. Obama. If this steadfast commitment to the actual rules represents a trend among her super support — and it likely does, despite the electoral vote Hail Mary — Clinton’s in real trouble. This also further supports Chris Bowers’ recent argument that the Democratic race will end on or soon after May 6, the day Sen. Obama most likely crosses the threshold of 1627 pledged delegates (a.k.a. 50% + 1 of the pledged total.)

Update: Add unaffiliated super and Tennessee Governor Phil Bredesen to those leaning Obama in the final analysis. “Bredesen also joined House Speaker Nancy Pelosi (D-Calif.) in warning that superdelegates should not overturn the outcome from primaries and caucuses.” And Harry Reid, at least, also seems to think there’s an exit strategy before the convention: “I had a conversation with…[Howard] Dean today. Things are being done.Update 2: Uncommitted and Clinton supers are not amused. Update 3: See also Clinton super Joe Andrew.

Richardson: Time to Call it.

“My affection and admiration for Hillary Clinton and President Bill Clinton will never waver. It is time, however, for Democrats to stop fighting amongst ourselves and to prepare for the tough fight we will face against John McCain in the fall. The 1990’s were a decade of peace and prosperity because of the competent and enlightened leadership of the Clinton administration, but it is now time for a new generation of leadership to lead America forward. Barack Obama will be a historic and a great President, who can bring us the change we so desperately need by bringing us together as a nation here at home and with our allies abroad.

Big news this Good Friday: Governor Bill Richardson will endorse Sen. Obama today. In his letter to former supporters, Richardson specifically cites Obama’s speech on Tuesday. “Earlier this week, Senator Barack Obama gave an historic speech. that addressed the issue of race with the eloquence, sincerity, and optimism we have come to expect of him…Senator Obama has started a discussion in this country long overdue and rejects the politics of pitting race against race. He understands clearly that only by bringing people together, only by bridging our differences can we all succeed together as Americans.” Mr. Richardson, your position is a messenger pigeon.

Breaking News: The Obvious.

“The irony to all of this, of course, is that while the mechanics of the Democratic nomination fight overwhelmingly favor Obama, the media is giving Clinton a huge lift. And this comes after a year of Clinton complaints that the media was doing them more harm than good.” MSNBC’s Chuck Todd argues that the press may be the only thing keeping Clinton in it (and that the supers may not much like Clinton anyway.) Gee, you think?

In related news, the NYT’s Adam Nagourney argues Clinton’s path to the nomination has gotten harder, now that Michigan and Florida don’t appear to be revoting. “If there is a road to victory for Mrs. Clinton, it is a fairly narrow one.” Emphasis there on “If.” But, hey, at least they’re starting to figure it out. Update: CNN also gropes toward the math.

Supers, get Supering. | Pork King for Clinton.

“In Washington, there’s no happier situation for a politician than to be doing absolutely nothing and getting great press for it. But let’s be clear about one thing: keeping their powder dry profits the superdelegates, but comes at the expense of their party. It shouldn’t take Solomon to see that.The Atlantic‘s Josh Green argues that the superdelegates should get cracking on their decision, if they’re serious about a long race hurting the Dems.

And, in related news, Sen. Clinton picks up her first two superdelegates in a month: DNC rep DNC rep. Pat Maroney of WV and, more notably, Rep. John Murtha of PA. Murtha, a.k.a. “the Pork King,” has not only been an enemy to ethics reform, but has a litany of shady scandals to his name, from Abscam to PAID. (Not for nothing did CREW name him one of the 20 most corrupt representatives in Congress.) And, of course, Murtha led the House in earmarks last year, clocking in at $162 million (thanks to his gig as the Appropriations Defense Subcommittee Chairman.) So, given that he’s part of the problem and not part of the solution, I’m not at all surprised he’s chosen to endorse the candidate who’s rife in lobbyist money and who won’t release her own earmarks. That’s one super you can have, Sen. Clinton.

Anxious in Superland.

“‘A key question to me is how the candidates would affect the down-ballot races,’ said Steven Achelpohl, the Democratic state chairman in Nebraska. ‘I think Obama would have a more positive impact on our other races out here in Nebraska.’” The NYT surveys the general mood among undecided supers at the moment, and finds them mostly nervous and looking for closure. “While many superdelegates said they intended to keep their options open as the race continued to play out over the next three months, the interviews suggested that the playing field was tilting slightly toward Mr. Obama in one potentially vital respect. Many of them said that in deciding whom to support, they would adopt what Mr. Obama’s campaign has advocated as the essential principle: reflecting the will of the voters.” Good. I figured the opinion that Oregon super Bill Bradbury voiced in the WP would not be a common one, and particularly now that Pelosi has weighed in to the contrary.

The FL/MI Smoke Machine.

“Contrary to the gullible media’s belief that ‘time’ is a ‘powerful ally’ on Clinton’s side, in fact, Clinton’s only ally is uncertainty. The minute it becomes clear what will happen with Michigan and Florida — re-vote them, refuse to seat them, or split them 50-50 or with half-votes, as some have proposed — is the minute that Clinton’s last ‘path to the nomination’ closes. The only way to keep spin alive is to keep uncertainty alive…Penn can claim that there is a path to the nomination, but under any possible actual resolution of the uncertainty, there is not.”

TAP’s Mark Schmitt explains Clinton’s FL/MI strategy: prolong the chaos. “[T]he specific resolution doesn’t matter, because whatever it is, it will introduce certainty and finiteness, and without the comfort of ambiguity, the Clinton spin-campaign cannot survive. The Clinton campaign began — unwisely — by spinning inevitability; it ends, equally unwisely, by spinning cosmic uncertainty. In between the two spin campaigns, they apparently forgot to give people enough of a positive reason to actually vote for Senator Clinton.

Update: It’s out of this same desire to muddy the waters, says Al Giordano, that the Clinton camp is now trying to put the brake on the Texas caucus results: “Only by generating smokescreens can it obscure from everybody’s view that Clinton has ceased to advance in national convention delegates while party leaders – from the national to the local – continue to converge in a near-consensus that Obama is the nominee that has earned it, that the voters most support, and that they view as most able to defeat McCain in November.

Pelosi: It’s Over.

“‘If the votes of the superdelegates overturn what’s happened in the elections,’ said Pelosi, ‘it would be harmful to the Democratic Party.’” Following up on her recent dismissals of the so-called “dream ticket”, Speaker Nancy Pelosi reaffirms that the pledged delegate leader (i.e. Obama) will be the supers’ choice for nominee. “But what if one candidate has won the popular vote and the other candidate has won the delegates?” asked Stephanopoulos. ‘But it’s a delegate race,’ Pelosi replied. ‘The way the system works is that the delegates choose the nominee.‘” Game, set, and match.

Stepping Back for the Big Picture.

With a six-week lull between now and the next contest, during which I hope to spend more time focusing on Harold Ickes than on Harold Ickes (sorry, dissertation humor), now’s a good chance to buck Mark Penn and refocus on the macrotrends in the primary race right now:

For one, superdelegates are clearly trending towards Obama. “Among the 313 of 796 superdelegates who are members of Congress or governors, Clinton has commitments from 103 and Obama is backed by 96, according to lists supplied by the campaigns. Fifty-three of Obama’s endorsements have come since he won the Jan. 3 Iowa caucuses, compared with 12 who have aligned with Clinton since then…[Since Ohio/Texas] the Illinois senator has won backing from nine superdelegates and Clinton one, according to the campaigns and interviews.” (Speaking of which, he picked up another one today in Wisconsin’s Melissa Schroeder. As you probably know, you can keep track of the supers over at DemConWatch.)

For another, whatever sound and fury Mark Penn tries to kick up about Pennsylvania and electability, it’s a tale told by an idiot, signifying nothing. In the most recent general election poll of the state, Obama still does better than Clinton against McCain there (although, thanks to all the recent negative press, McCain has moved ahead of both since this poll.) To his credit, Clinton supporter and Pennsylvania Governor Ed Rendell, off-message once again, today conceded Obama can take PA over McCain. (And in any case, as Michael Dukakis can tell you, past primary performance is often not a valid predictor of future outcomes.)

Otherwise, Obama is up in the daily trackers, although those tend to be volatile. Most importantly, obviously, Sen. Obama enjoys a sizable, if not insurmountable, lead in pledged delegates, votes, and states, so we’re in very good shape, despite what ever sad butchering of reality emanates from Camp Clinton these days. So keep your chin up, y’all. If you got money, donate. If you got time, phonebank, write your supers, and/or get the message out. Let’s press this thing home.

By the way, while looking for a good Penn-Microtrends link above, I found this NYT book review that begins with an anecdote about the TV show Numb3rs: “‘There’s no way the bad guys can win,’ my son assures me each time we watch the show together. ‘They can’t do the math, Dad.’” Truer words have never been spoken.
