Pawlenty: Obama the 'Barney Fife' of presidents

Pawlenty, who abandoned his own bid for the GOP nomination after a disappointing finish in an August straw poll in Ames, Iowa, endorsed Romney in September and has been one of his most prominent surrogates in the primary race.

"There is one candidate in this race who was the depth and scope of experience in the private sector, as a job creator, as a leader in business, to get this country turned around," Pawlenty said, "and that is Mitt Romney."
