“Some supporters said they had discussed how to raise with Clinton the subject of withdrawing from the race should she fail to win decisively on March 4. One option was to wait a day or two and then dispatch emissaries to former president Clinton to urge him to make the case.” Despite the show of bravado regarding Florida and Michigan this morning, the WP reports that Sen. Clinton is well aware the end is nigh. “One adviser, who spoke on the condition of anonymity to speak freely, said Obama’s 17-point Wisconsin victory on Tuesday had started to sink in as a decisive blow, given that the state had been viewed weeks earlier as a level playing field. ‘The mathematical reality at that point became impossible to ignore,’ the adviser said. ‘There’s not a lot of denial left at this point.’ Despite Clinton’s public pronouncements of optimism, this adviser said: ‘She knows where things are going. It’s pretty clear she has a big decision. But it’s daunting. It’s still hard to accept.’” Update: The NYT has more of the same, but that isn’t stopping Sen. Clinton from upping the ante on Tuesday’s debate.
