Numerically, it's starting to like like Hillary's going to have a hard time pulling it off. Apparently Obama's pretty competitive in Texas and Ohio and, even if he doesn't win, he's still going to get a significant fraction of the delegates. With his current lead, Hillary's going to have to win big in order to get back out in front.
I think at this point, it is improbable that Hillary will win the necessary votes in the remaining states to give her a win. About her only option is convincing the delegates not to vote for Obama and to ignore the will of the Democratic voters.
Although I'm not especially fond of Clinton, I always wonder where comments like this come from. Is there a basis for believing that she's insanely power-hungry and was only using Bill to get to the presidency herself, or is it just one of those things that people started saying, after which it got repeated so much that everyone now assumes it's true?
She'll be the nominee. Trust me on that. She may henceforth be known as the Grinch who Stole Christmas, but she'll win; don't worry one little bit about that.
My understand is that Texas has a system in place to encourage participation by making a districts amount of delegates be dependant on percentage participation (to an extent). So if you have two districts with the same population, but one has a high voter turn out and other low, the high one gets more delegates. So basically, while Clinton will likely win the popular vote in TX, Obama can win the delegates.
Even Clinton winning the popular vote is far from sure, according to some of what I'm seeing: (From here.) If they were already pretty even last week, then it's a fairly safe bet that Obama will be ahead before the primary actually comes up. He has money, and momentum, and an image right now. Clinton has significantly less of all of that. My guess is she's done, and personally that suits me just fine. From the time I heard her say, years ago when Bill was in his first term, that their goal was to do 12 years in the White House, 8 with him as president and 4 with her as president, I have been opposed to that woman. This is a blatant attempt to get around the Constitution. When Republicans do stupid stuff to try to get around the Constitution, the Democrats (rightly) scream about it. I can't understand why nearly half of them are in favor of the Clintons doing it.
