The latest CBS poll has white evangelicals choosing McCain over Obama 58 percent to 24 percent, with 15 percent undecided. If the undecided break 50-50, that would give Obama nearly one-third of the white evangelical vote–a big improvement over Kerry’s performance in 2004. For him, opportunity knocks. McCain, by contrast, has got to ratchet up his evangelical outreach. By the Republican Convention he should have locked up this part of the GOP base, and as of now he hasn’t.
