Two-thirds of those who watched Thursday night's speeches at the Republican National Convention already had decided who they would vote for before anyone opened their mouth, but among the small but important group of persuadable speech watchers, there is 2:1 movement towards Romney, according to a SurveyUSA poll of the state of Florida conducted for WFLA-TV in Tampa.

1,211 adults were interviewed statewide 08/31/12, after Romney, Florida's Marco Rubio and Clint Eastwood spoke to the convention 08/30/12. Of the adults, 1,100 were registered to vote in Florida. Of the registered voters, 754 heard the convention speeches. Of the convention speech watchers:

* 66% did not change their mind.
* 16% switched from "undecided" to Romney.
* 6% switched from Obama to Romney.
* Adding those 2 together, that's 22% who switched TO Romney.
* 10% switched from "undecided" to Obama.
* 2% switched from Romney to Obama.
* Adding those 2 together, that's 12% who switched TO Obama.
* Comparing the 2 aggregate numbers: 22% switched TO Romney, 12% switched TO Obama.

Caution: As expected, those who watched the speeches at the Republican National Convention were disproportionately Republican. This poll does not attempt to measure how all likely voters in the state of Florida would vote if filling out a ballot today. It attempts to measure early movement among speech-watchers only.

Reaction to individual speeches broke along party lines:

* 79% of Republicans, compared to 35% of Democrats, said Romney's speech helped his chances to be elected.
* 12% of Republicans, compared to 45% of Democrats, said Eastwood's speech hurt Romney's changes to be elected.
