Rick Santorum is sick of the back and forth fighting between Mitt Romney and Newt Gingrich. The presidential hopeful, who took third place in Florida's primary, told supporters Wednesday in Nevada, "The American public does not want to see two or three candidates get into a mud-wrestling match where everybody walks away dirty and not in a position to represent our party proudly." Santorum argued that instead of duking it out with one another, Republicans should present a united front against President Obama if they expect to beat him in the general election.
