Paul and Tancredo said they would not necessarily support the GOP nominee. That is interesting. Does this feeling persist within the Republican Party? Is that bad news for Giuliani? Maybe. Maybe not. Brownback, the "values candidate" said no matter what he would support the nominee -- however grudgingly.
I heard Ron Paul specifically dismiss the possibility of running as a Libertarian in 2008, just last week on the Ed Schultz Show. My own speculation regarding third party challenges is here. Continuing:
... there was the waffling by Ron Paul and Tom Tancredo at the GOP debate about whether they'd support the eventual GOP nominee. Remember, it wouldn't take more than a percentage or two in some states for a third party candidate like Paul or Tancredo to cost the GOP a whole bunch of Bush '04 states out West.
There's also potential for the Christian conservatives to peel off and find a candidate, possibly *choking back maniacal laughter* Rick Santorum.
It appears that the GOP nationally is in the early stages of a major meltdown. Couldn't happen to a nicer bunch.
