Poll: Birth control not a top election issue for US voters

Voters in the US say health care, unemployment, the federal deficit, international issues and gas prices will help influence their decision ahead of the presidential election -- but just one in five thinks birth control policies are an important factor, a Gallup poll out Monday found.

The poll also saw President Barack Obama record his biggest lead yet over Republican frontrunner Mitt Romney after voters were asked who they would vote for were an election held today.

Forty-nine percent said they would vote for Obama, while 45 percent would choose his likely opponent Romney. The pair were tied at 47 percent in the last poll taken in mid-February.
