Beware Pennsylvania Tunnel Vision.

"Simply put: If Obama (and supporters) set expectations for a knockout punch in Pennsylvania, they will be giving oxygen to a gasping Clinton machine on its last breaths. But if they keep Pennsylvania in perspective (no single state has determined the nomination, although New Hampshire, Nevada, and Ohio were all frantically seen and spun as such in their moments), they’ll emerge from the coming Pennsylvania Clinton victory – a kind of Last Hurrah for the politics of the last century – to cross into the 21st century beginning in early May." I added this link to the post below, but in case you missed it: Al Giordano crunches the numbers and argues that focusing on the Keystone State is not the way to go.

Along related lines, Obama campaign manager David Plouffe downplayed the importance of PA today: "Pennsylvania is only one of 10 remaining contests, each important in terms of allocating delegates and ultimately deciding who are nominee will be." (And before anyone argues that this broader focus means Obama can't win Pennsylvania in the general, take a look at the polling there. As in many other states, Obama does significantly better against McCain in Pennsylvania than does Clinton.)
