My paraphrases:

From Mike Huckaby, former AR Governor (in references to the way government spends money):

“The Congress spends money like John Edwards in a beauty shop.”

From Tancredo (on the many political conversions by other candidates):

“I trust conversions when they are on the road to Damascus, not the road to Des Moines.”

Romney (on immigration):

“The McCain-Kennedy immigration bill could end up doing for immigration what McCain-Feingold has done for campaign finance reform.”
