From Politico:

“Republican presidential nominee Mitt Romney lost women to Barack Obama by 11 percentage points in the 2012 election, and the 2013 campaigns saw a similar trend. A series of recent polls show a continued double-digit lead for Democratic candidates among women, with the margin soaring to much higher levels among single female voters. The GOP — which lost female voters by large margins in every competitive Senate race in the 2012 election — also saw a 10-point increase in its unfavorability rating among women to 63 percent, according to an October ABC/Washington Post poll.”
