Looks like Obama has scared the Christian right into uniting behind McCain:

At a meeting Tuesday in Denver, about 100 conservative Christian leaders from around the country agreed to unite behind the candidacy of John McCain, a politician they have long distrusted, marking the latest in a string of movements that bode well for McCain’s general election prospects among the Republican base.

A second person who attended the event, but asked not to be named, said that the group was motivated principally by a desire to defeat Barack Obama. “None of these people want to meet their maker knowing that they didn’t do everything they could to keep Barack Obama from being president,” the participant said. “You’ve got these two people running for president. One of them is going to become president. That’s the perspective. That that’s the whole discussion.”

It probably helped that McCain moved to the right a little bit on the gay marriage amendment in California (which may or may not be a flip-flop depending on your view 🙂 I bet it made supporting him a little easier for the Christian right.
Even though the Evangelical vote is fractured this year between those who oppose abortion and gay marriage and those who want to focus on the poor and the environment, the support of the Christian right leaders could actually help McCain if they can energize their organizations as well. Their organizations are a good source of grassroots support, which were used by the Bush campaign to get Evangelicals to the poll and they are also a good source of campaign workers, working the phones and going door to door. When they’re energized and working to get someone they believe in elected, they will work diligently. But I’m not sure they will be able to get behind McCain the way they got behind Bush given McCain’s treatment of them and their issues. I guess the way they’ll energize the base is in opposition to Obama, not really support of McCain (that’s what Dobson did).
It will be interesting to see how this all plays out in November, won’t it?
