I find that hard to believe.
I don't.... Many Evangelicals simply will not for Romney because he's a Mormon, thus Obama wins by default if they withhold their vote.
Further, Evangelicals have been "invaded" by false teachers and Preachers so it's no surprise they would also be mis-lead in who "else" they might support.
Additionally ...Healthy Preaching overall is lacking in many churches so the "flock" is not well fed...in many cases starving for truth because their Pastors are not themselves well fed.
..and the list can and does go on.
But then we were told these things would occur as that day approaches. ...even among our own...in fact directly spoken by Christ they would come from us.
Note that the 22% figure is what they say he would receive this time - which i also think is wrong and highly presumptuous - not what they gave in 2008.
