A prominent Christian leader whose radio and magazine outreaches are solidly in support of biblically-based marriages – and keeps in touch with millions of constituents daily – says he cannot consider Arizona Sen. John McCain a viable candidate for president.

"Speaking as a private individual, I would not vote for John McCain under any circumstances," said James Dobson, founder of the Colorado Springs-based Focus on the Family as well as the Focus Action cultural action organization set up specifically to provide a platform for informing and rallying constituents.

He noted that legislation he'd just been discussing on the program, regarding an attempt by Democrat leaders in Congress to create obstacles for ministries such as Focus to reach constituents with action messages about pending legislation, is being supported by McCain, too.

"That came from McCain, and the McCain Feingold Bill kept us from telling the truth right before elections … and there are a lot of other things. He's not in favor of traditional marriage, and I pray that we won't get stuck with him," Dobson said.
