Lets see. You are saying that everyone who endorsed Romney over McLame in 2008 is not to be trusted? You do know that Romney is more conservate than McLame right? So everyone whe every endorsed Romney in 2008 is off your list? You know that includes:
Jim DeMint
Tom Tancredo
Jim Talent
Also From Wikipedia:
As of November 5, 2007, The Hill’s running tally of endorsements from members of Congress showed Romney leading McCain 38 to 28 for the lead among Republican candidates.[102] Conservatives in the Republican coalesced around Romney after the January 29 Florida primary. Former Pennsylvania Senator Rick Santorum endorsed Romney on the talk radio show of Laura Ingraham. The talk radio community, Rush Limbaugh, Sean Hannity, William Bennett, Mark Levin, Dennis Prager, Glenn Beck, Hugh Hewitt and Laura Ingraham endorsed Romney, in an anti-McCain move. In spite of their efforts, Romney was out of the race and McCain became the presumptive nominee less than two weeks after Florida
Looks like Rick was in good company and you have a mouth full of sour grapes.
