If you consider the pro-life/pro-gun wing of the base as “not much”?
My feeling, since I don't believe Huckabee is sincere about any position he takes, is that in the long run he wouldn't deliver either the pro-life or the pro-gun types, except for ones who are easily fooled. Again, I don't think that Huckabee believes anything he's saying, nor has he ever. He's a con man. I've seen all too many of them in the evangelical movement, folks like Jim Bakker. There are too many like that and far too few like Billy Graham or his son Franklin (or my late Uncle William). And it's not new. Think of Aimee Semple McPherson or any of a thousand charlatans through history, such as Simon Magus.
There are lots of folks who invoke the name of Jesus who aren't truly followers of Jesus, regardless of what church they attend.
Huckabee is Jimmy Carter, not Ronald Reagan. He'll talk a good game until he gets elected, then watch out. I have a friend who was in his church when Huckabee was still a minister. He really liked him and thought highly of him. But he insists that Huckabee changed when he became governor. We talked for awhile and decided that the "bad" Huckabee that emerged as Governor was the real person and that the "good" Huckabee from his ministry was the act. Huckabee's just putting on his old act again.
I just said that very thing to one of my girls on our way to brunch.
As true in many situations, often the convert has the strongest commitment to the new faith or position. For Romney to acknowledge that he has moved from a pro-choice to a pro-life position is a plus in my book. He thought about the issue and revised his perspective. That is a flip, but not a flipflop.
