McCain will be lucky to win one primary. Has he ever done well in NH? He could maybe win the Iowa caucus, but he won't win a single southern or western state. Hell, even in blue states, the blue ppl will be voting in the other primary. The red ppl will vote red. McCain has NO chance at all.
If Bill Bradley had been a little more exciting as a candidate, maybe he would have drawn a lot of the votes that went to McCain, so that Bush and Bradley would have been the NH winners, and Gore would have had a harder time winning the Democratic nomination, and Bush would have had an easier ride to the Republican nomination.
I don't know if McCain did well in any primary in 2000 where only registered Republicans could vote in the Republican primary.
