A series of wobbly debates and heightened scrutiny of Rick Perry’s record have conservatives second-guessing the Republican front-runner heading into Saturday’s high-stakes Florida straw poll.

Diane Tropia came to Presidency 5 unsure whom she liked: Mitt Romney or Perry. Thursday night’s debate provided clarity.

“(It) definitely solidified my vision of Romney,” said Tropia, 46, of Jacksonville. “He’s very presidential.”

The reaction Friday, at this sprawling convention of conservatives in a state critical for winning the presidency, underscored growing doubt among conservatives nationally that Perry is the strongest candidate to confront President Barack Obama.
