To the best of my knowledge, Romney is not visiting Christian churches.
He and his people have decided they can win this without the Christian Right.
They can't do this without the Christian Right. In 2010, white Evangelicals constituted 34% of the turnout.
Romney can't win the South without the Christian Right.
And his only win in a primary in 2008 & 2012 outside of his home turf is Florida & AZ...FL due to the elderly vote...
