Poll: Obama opens significant lead in swing states, thanks to women voters

In the fifth Swing States survey taken since last fall, Obama leads Republican front-runner Mitt Romney 51%-42% among registered voters just a month after the president had trailed him by two percentage points.

The biggest change came among women under 50. In mid-February, just under half of those voters supported Obama. Now more than six in 10 do while Romney’s support among them has dropped by 14 points, to 30%. The president leads him 2-1 in this group…

Republicans’ traditional strength among men “won’t be good enough if we’re losing women by nine points or 10 points,” says Sara Taylor Fagen, a Republican strategist and former political adviser to President George W. Bush. “The focus on contraception has not been a good one for us … and Republicans have unfairly taken on water on this issue.”
