GOP presidential debate

Texas Governor Rick Perry struggled to answer his critics in the last debate between the Republican contenders, identify Achilles heel, which undermines its way to the presidential nomination of the party.

As in the previous two debates, as he entered the race, settled performance Perry saw how he walked on stage, his main rival, former Massachusetts Governor Mitt Romney, who twice ignored Perry, distorted efforts to attack him, saying scornfully: “Nice try.”
