In the 2012 presidential election, President Barack Obama could double the amount of support he got from evangelicals in the 2008 election, according to Barna Group, a Christian polling organization. In 2008, Obama received the support of about 11 percent of evangelicals, according to Barna Group. In a March 14-21 Barna Group poll of 647 likely voters, twice as many evangelicals, 22 percent, said they were prepared to vote for Obama. http://www.christianpost.com/news/poll-evangelicals-may-double-their-support-for-obama-in-2012-election-72657/
Although there probably are some, I don't know any Evangelicals that would vote for Obama (at least none that admit to it openly).
