Well, Medved & Hewitt have LONG already been in the tank for Romney...Hewitt was back in '07.
But you're right, Ansel...even talk show host Dennis Prager wrote a recent appeal to Evangelicals/Christians asking them to not consider Mitt's Mormonism.
Prager hasn't endorsed Romney. He says he realizes Evangelicals consider Mormonism to be a "cult." And he sides with Evangelicals being annoyed over the Mormon claim that they are "Christians," too. He understands that because he doesn't like it when Messianic Jews say, "We're Jews, too." (He thinks they should "id" themselves as Christians...I just wish Mormons would understand this as well...they don't like it when fundamentalist mormons are id'd as Lds)
But Prager is one of those "electability" voters I referenced in a post (I think on another thread this a.m.) -- where their #1 criteria is anti-Obama.
There is no way that it cannot happen, it will have to happen.
