After grousing for months, Republicans are growing more satisfied with their choices for president and, so far, they like what they're hearing from the newest candidate, Texas Gov. Rick Perry.An Associated Press-GfK poll released Friday found that two-thirds of Republicans and right-leaning independents are pleased with the party's presidential field, compared with just half in June. And they're paying more attention, with 52 percent expressing a “great deal” of interest in the Republican nomination fight — compared with 39 percent earlier this summer — after a period that saw Perry enter the race and Michele Bachmann win a key test vote in Iowa, the lead-off caucus state, threatening frontrunner Mitt Romney's standing at the top of the pack.The poll shows Perry — who has never run a national campaign and is just now introducing himself to most people — benefiting from wall-to-wall news coverage over the past few weeks as he became a candidate and jostled the until-then sleepy contest. Just 12 percent of Republicans and right-leaning independents have a negative impression of the Texas governor. And 63 percent of Republicans view him in a positive light, compared with 33 percent in June.Beyond that, Republicans didn't change their impressions much about Romney. Nearly 2 in 3 still view the former Massachusetts governor positively, while just under a quarter view him negatively as he runs a cautious, methodical campaign that's facing its first true test in Perry.Bachmann, the Minnesota congresswoman who won the Iowa straw poll, got roughly the same marks as Romney now that she's boosted her national profile. Both her positive and negative ratings rose in the two months since she entered the contest and started to become better known.Broadly, the results suggest that Republicans are coming around to the idea that there may be a winner in the bunch after being less than enthusiastic for months and even though party elders continue to grouse that the field lacks a candidate strong enough to take on President Barack Obama. As recently as this week, New Jersey Gov. Chris Christie, Wisconsin Rep. Paul Ryan and former Florida Gov. Jeb Bush — again — insisted they weren't running for president despite urging from supporters.Sarah Palin, the 2008 Republican vice presidential nominee, says she'll announce in late September whether she will run. Still, while Republicans like them are warming up to the field, the overall population still has significant doubts and is largely unimpressed, which could bode well for Obama come the general election.
