FILE - This Oct. 3, 2012 file photo shows Republican presidential candidate, former Massachusetts Gov. Mitt Romney patting moderator Jim Lehrer on the back at the end of the first presidential debate with President Barack Obama in Denver. When it comes to debates, Mitt Romney loves the rules. The eyes of millions of voters upon him, the Republican candidate is quick to poke holes in his rival's arguments. But he's just as ready to take the moderator to task when he believes the predetermined ground rules have been breached.
