Women boost Obama over Romney in swing states April 02, 2012|Lily Kuo | Reuters WASHINGTON (Reuters) - Women voters helped President Barack Obama take a large lead over Republican front-runner candidate Mitt Romney in a dozen battleground states, a USA TODAY/Gallup poll said on Monday. The results point to difficulties the Republicans could face among a critical bloc in November's general election against Obama. Support for Obama among women under the age of 50 surged from mid-February, the poll found, putting the president ahead of Romney by 51 percent against 42 percent among all voters. Obama led Romney among the women with 54 percent, compared to Romney's 36 percent.
