Via Ballot Box:
Newt Gingrich stands to benefit if Herman Cain were to withdraw or lose support in the Republican presidential race, according to a Public Policy Poll released on Tuesday.
Gingrich has a much better favorability rating with Cain supporters than does Mitt Romney. Seventy-three percent of Cain supporters view Gingrich favorably, while only 33 percent have a favorable view of Romney.
Gingrich is also the consensus second choice among Cain voters, with 37 percent saying Gingrich would be their back-up to Cain, compared to 14 percent for Michele Bachmann, 13 percent for Romney, and 12 percent for Perry.
