How McCain Lost in Pennsylvania - New York Times
...in Pennsylvania, 27 percent of Republican primary voters didn't just tell pollsters they would defect from their party's standard-bearer; they went to the polls, gas prices be damned, to vote against Mr. McCain. Though ignored by every channel I surfed, there actually was a G.O.P. primary on Tuesday, open only to registered Republicans. And while it was superfluous in determining that party's nominee, 220,000 Pennsylvania Republicans (out of their total turnout of 807,000) were moved to cast ballots for Mike Huckabee or, more numerously, Ron Paul. That's more voters than the margin (215,000) that separated Hillary Clinton and Mr. Obama.
For all the noise about democrats not supporting each other, the news has taken little notice of the republicans who aren't supporting McCain. Despite the noise from the press, I doubt dems will not support the ticket even if their candidate isn't on top... However, I don't think that's true of republicans: especially the "values voters"
Whoever gets the democratic nomination will win ... even if its Hillary (whom most conservatives hate - in a visceral sense)
