Nothing is carved in stone

From The New York Times:

With Senator Barack Obama vowing to challenge Senator Hillary Rodham Clinton on her home turf, the Democratic presidential primary in New York on Feb. 5 is shaping up as the state’s most competitive since 1992, when Bill Clinton took up a rival’s mantra of change to all but cinch the nomination.

Mrs. Clinton was re-elected a little more than a year ago by better than two to one. Before the Iowa caucuses, she had so dominated opinion polls and endorsements by elected officials and powerful unions that many considered her home state impregnable to political interlopers.

But if Mr. Obama wins the South Carolina primary in two weeks, he could develop enough grass-roots support among young people, liberals and black voters in New York to pose a serious threat to her claim to the state’s rich delegate lode, allies of both candidates say.

“The expectation is that Hillary should win in New York,” said Assemblyman Adam Clayton Powell IV of Harlem, an Obama supporter. “As you know, expectations don’t always translate into votes, and so we’re going to fight in New York.”

There are all manner of "experts" who will say that this or that "must" happen or cannot happen. All of it is bull. If enough Democrats want Obama then he will get the nomination. If enough Republicans want Fred Thompson then he will get the nomination. It is just that simple.
