Michael Goodwin thinks that tomorrow's election is not so much Hillary's last stand as it is Obama's last chance:

This is Barack Obama's third chance to knock her out. If he can't close the deal this time, maybe he can't close the deal, period.

Either the third time is the charm for him, or it could be strike three against him. Any result tomorrow that doesn't finish her off lets her argue that Democratic voters' love affair with Obama was just one of those flings. She'll say buyer's remorse has set in, and it's time to get serious about winning the White House.

She'll also bring up her wins in the disputed Michigan and Florida primaries and repeat her vow to fight for those delegates.

Given the wacky past two months, those arguments would keep her alive. They start with the claim that even a split decision tomorrow would fit a pattern showing voters can't commit to the Illinois rookie.

Clinton's husband, former President Clinton, has asserted that his wife must win both Texas and Ohio to keep her campaign alive. On Friday, Hillary Clinton's advisers recast the stakes, saying if Obama lost any of the four presidential primaries Tuesday--Rhode Island and Vermont also vote--it would show Democrats are having second thoughts about him.

And of course Hillary and Ickes will close in on the superdelegates.
