A new ABC News/Washington Post poll has 49% of Americans viewing Romney unfavorably while just 40% see him favorably. That's 10-straight polls where Romney's unfavorable rating is larger than his favorable.
Barack Obama has a 53% favorable rating, but most of that comes from women, who give him a 58% positive rating. Only 47% of see him favorably.
Historically, Romney's low ratings could be cause for concern.
Negative views of Romney are 11 points higher than they were for Bush 24 years ago. (Twenty-two percent had yet to form an opinion of Bush, double the undecided on Romney.) And Bush’s 41 percent was an election-year low, while Romney’s 40 percent is a point from his high this cycle.
On incumbents, favorable views at this point in the race have varied widely in the past. Obama’s rating is lower than that of most previous incumbents; but even among registered voters, his rating now is no worse that George W. Bush’s 47 percent in midsummer 2004, a race Bush won.
