"More Voters Considering Romney Than Obama, Perry."

A new Gallup poll.

Though Romney currently receives the highest level of consideration among voters, more say they would "definitely vote for" Obama (33%) than say this about either Romney (21%) or Perry (20%). That may reflect the virtual certainty that Obama will be the Democratic candidate for president, while Republicans' loyalties are divided between their two leading contenders.

This means that Romney also has a much smaller "definitely not vote for" number than either Obama or Perry.
