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.
"The focus on contraception has not been a good one for us," explains Republican strategist Sara Taylor Fagen.
Of course, Republicans have long talked medieval on a number of social issues, talk which a lot of voters just dismissed as the stuff Republicans had to say to win their own base, but would never ever really attempt to impose. It was kind of a game. And as long as Republicans kept taxes low, a lot of socially progressive voters were willing to play along.
Not anymore. On issue after issue, no matter how extreme, Republicans nationwide seem intent on delivering to their crazy base exactly what they're promising. The same party that is passing legislation to force transvaginal ultrasounds on women in state after state, is also promising to take away access to birth control. So why shouldn't women believe them?
Which is bad news for Republicans as long as women are still allowed to vote.
