A new Quinnipiac national poll finds Mitt Romney leading the Republican presidential field with 22%, followed by Herman Cain at 17% and Rick Perry at 14%. All other candidates are in the single digits.
Said pollster Peter Brown: "After seeing his lead disappear with the entrance of Rick Perry into the trace, Mitt Romney has regained his position out front as the Texas governor's fortunes have fallen. The GOP race, however, remains quite open... A big question now is whether Herman Cain is a serious candidate for the nomination. He has zoomed into second place ahead of Perry."
