Assuming, for a moment, that Obama does sweep on Tuesday, which seems likely and even team Clinton has admitted as much, those twenty three states will include the last eight primaries and caucuses, the last few of which have been lopsided massacres in which Hillary has rarely made 40 percent of the vote. It's interesting to note that even though most consider McCain the presumptive nominee, he isn't sweeping the Republican contests like Obama is doing on the Democratic side. I understand the argument that the delegate difference is much wider on the GOP side, but still, the irony is palpable.
When you hear team Clinton talk about upcoming contests, one can tell they don't expect to have a realistic chance at a victory until March 4th in the Ohio and Texas contests. Of course, team Obama knows this and I am sure they will make a vigorous play for those states, assuming there still is a race at that point. The momentum Obama is building by piling up victory after victory, by March 4th is going to reach the strength of a Mega-Tsunami. There will be no victories for Hillary on March 4th if she has no wins between now and then.
I think it is time for Hillary and her team to start discussing their end game. If they get swept on Tuesday, barring some catastrophic event for Obama, Hillary is finished. To avoid having Super delegates decide the nominee at the convention, Hillary should concede at that point and allow the party to unite behind Barack Obama.
