While Public Policy Polling showed the Republican National Convention wasn't much help to Republican Mitt Romney in Florida, polling firm Survey USA conducted a survey for St. Petersburg's WFLA-TV that showed the RNC was effective -- for those who watched it.
A big difference between the polls: The Survey USA poll isn't a general or likely voter poll. It sampled far more Republicans than Democrats (who outnumber Republicans in Florida) because it gauged convention watchers. And most convention-watchers were Republicans.
Perhaps the most troubling aspect of all of this is that it shows how close-minded partisans have become. They flock to hear their side arm them with talking points and they eschew the other side.
Still, the poll has value, especially regarding independents (although, again, conservative-leaning independents might have been more likely to watch and vote GOP anyway). A clear majority of Independents found that Romney and Rubio's speech helped in relatively equal measures. But Clint Eastwood's odd and rambling speech wasn't as well received, with only 41 percent saying the Eastwood address helped Romney and 24 percent saying it hurt. Put another way, that's a 23 percent negative shift away from Romney when compared to the helped/hurt numbers for those who rated Rubio's speech.
