'Waitress Moms,' 'Walmart Moms' and Undecided Voters

Both parties agree that the 2012 presidential election is going down to the wire. President Obama and Mitt Romney are dashing from swing state to swing state in pursuit of this year's last undecided voters. Polls show they are women — predominantly white, non-college educated, working women who are the fastest growing part of a changing workforce — not the "soccer moms" of the prosperous 1990's. Obama accuses Romney of conducting "a war on women," but they've been moving in Romney's direction since after the first debate. Are they more concerned about abortion and contraception or the economy? How does "micro-targeting" help the candidates speak to the different needs of different women?
