WASHINGTON - US President Barack Obama has the edge over Mitt Romney in three key battleground states in large part because voters find him more likable than the Republican challenger, a poll released on Wednesday found.
Quinnipiac University's survey of more than 3,500 likely voters in the Nov. 6 US election found Obama ahead by 11 percentage points in Pennsylvania (53 to 42 percent), and 6 percentage points in both Ohio (50 to 44 percent) and Florida (51 to 45 percent). Obama won all three states in the 2008 presidential election.
At least 50 percent of respondents in the three states expressed a "favorable" opinion of Obama compared to about 40 percent for Romney, according to the poll, which has a margin of error of about plus or minus 2.9 percentage points.
The Obama campaign has tried to portray Romney, one of the richest men ever to seek the presidency, as out-of-touch with ordinary Americans.
