A George Soros-funded super PAC is vowing to send operatives to stake out Republican campaigns to hunt for and to record any gaffes or controversial statements the candidates may make.

On Tuesday, American Bridge sent a fundraising plea to supporters asking for money to pay for “trackers,” a term for political operatives who sometimes tail opponents..

“When our trackers caught Rep. Todd Akin in an interview talking about ‘legitimate rape,” his invitation to the Republican Convention in Tampa was revoked,” Rodell Mollineau, president of American Bridge said in the letter.
