So Obama has time and money. He's got momentum. And he's now demonstrated an ability to appeal to the demographic groups that were supposed to be Hillary's firewall in Texas, Ohio, and Pennsylvania. Hillary won't make it easy — and, yes, weird stuff can happen at any time in a campaign — but is there any question that Obama is now the frontrunner?
And one other thing: as I said the other day, if the race ends up in a dead heat going into the convention, then superdelegates should be free to vote for whoever they want to. But if Obama is ahead by more than, say, 200 delegates or so, the people really have spoken. Hillary would risk fracturing the party if she then tried to pull out a victory by holding floor fights over Michigan and Florida and twisting arms to get a lopsided win among the supers. Let's all pray it doesn't come to that.
