What we need to do is to legally wreck the next election (in the primaries if possible) of the two of three leaders of the RINOs in the Senate, like McCain, and the rest of the republicans in the Senate will fall in line.
mccain ain't up for re-election until 2010 and I would doubt he would run for re-election anyway if he is not the 2008 nominee since he is getting up in years.
