Polls show Obama with a large lead in Virginia. After the Virginia Vote is in tonight, and even with Clinton's superdelegate advantage, Obama is likely to have the higher delegate total though regardless of today's result Clinton and Obama will remain within dozens of delgates of each other.
Pennsylvania, Texas, and Ohio's importance are increasingly with each passing Obama victory. Most see all three of these big states as likely to go for Clinton. Some of last month's Ohio polls had Clinton more than 20 points over Obama, though recent Obama victories could change all that.
However, based on all the information available to date we are still predicting a narrow Clinton victory - probably at the convention - and probably with the announcement of Obama as Clinton's VP. This would be the killer combination for the democrats and likely make them virtually unstoppable in the general election against McCain and his likely running mate, Huckabee.
