Boehner, Cantor Back Family Research Council Campaign Against SPLC

A number of prominent Republicans have signed on to the Family Research Council’s “Start Debating, Stop Hating” campaign in response to a Southern Poverty Law Center report that labeled the Family Research Council a “hate group.”
…….
Ironically, the ad argues that “our debates can and must remain civil - but they must never be suppressed through personal assaults that aim only to malign an opponent’s character,” right after it refers to the SPLC as “the radical Left” that’s “spreading hateful rhetoric.”

The ad is undersigned by a number of leading Republican politicians, social conservative and mainstream alike: House Minority Leader John Boehner (R-OH), House Minority Whip Eric Cantor (R-VA), Rep. Michele Bachmann (R-MN), Sen, Jim DeMint (R-SC), Gov. Bobby Jindal (R-LA), Rep. Steve King (R-IA), and even Virginia Attorney General Ken Cuccinelli.

The ad also says:
“The surest sign one is losing a debate is to resort to character assassination.”
