Mitt Romney insists he isn't running for president again, but a new Quinnipiac poll suggests he'd be the GOP's most formidable candidate should he give it another go.
In the poll, Romney led Hillary Clinton 45 percent to 44 percent among registered voters— making him the only hypothetical Republican candidate to do so. New Jersey Gov. Chris Christie was the only other Republican to come close, trailing Clinton by a single percentage point, 43 percent to 42 percent.
It's still too early to draw sweeping conclusions about the 2016 race from horse race polls, though Quinnipiac's findings do suggest Romney would at least make for a competitive candidate should he run again.
