CNN reports:
According to the CNN/ORC International survey, which was conducted entirely after Romney added Ryan to the GOP ticket, 49% of registered voters in Wisconsin say they back President Barack Obama, with 45% supporting Romney. The president’s four point advantage over the presumptive Republican presidential nominee is within the survey’s sampling error.
Two other polls conducted last week, before the Ryan announcement, indicated the president holding a single digit advantage in a state he won by 13 points in the 2008 presidential election.
…
But the survey does indicate Ryan’s popular in his home state. His favorable rating, at 50%, is actually higher than Romney’s, and 56% of all Wisconsinites say that Ryan is qualified to serve as president if necessary, and most rate Romney’s pick of Ryan as excellent or pretty good.
As Noah noted, a Rasmussen poll showed Romney a point ahead of Obama, 48 percent to 47 percent.
One advantage of Wisconsin’s slew of elections in recent months is that the Republican ground game in the state is excellent. And the GOP hasn’t slowed down: all the offices that were opened for the recall election have remained open, with the focus shifting to November. If the race between Obama and Romney in Wisconsin is close, that well-developed ground game on the GOP side could prove a crucial asset.
