Dobson on Thompson

I've been down on Dobson for a while now (link), but his latest comments judging whether Fred Thompson is a real Christian or not seem to be a new low. I know many people look to Dobson as a leader among Christian evangelicals, but to me his credibility is gone. From an article by Dan Gilgoff in US News and World Report:

Focus on the Family founder James Dobson appeared to throw cold water on a possible presidential bid by former Sen. Fred Thompson while praising former House Speaker Newt Gingrich, who is also weighing a presidential run, in a phone interview Tuesday. "Everyone knows he's conservative and has come out strongly for the things that the pro-family movement stands for," Dobson said of Thompson. "[But] I don't think he's a Christian; at least that's my impression," Dobson added, saying that such an impression would make it difficult for Thompson to connect with the Republican Party's conservative Christian base and win the GOP nomination. Mark Corallo, a spokesman for Thompson, took issue with Dobson's characterization of the former Tennessee senator. "Thompson is indeed a Christian," he said. "He was baptized into the Church of Christ." In a follow-up phone conversation, Focus on the Family spokesman Gary Schneeberger stood by Dobson's claim. He said that, while Dobson didn't believe Thompson to be a member of a non-Christian faith, Dobson nevertheless "has never known Thompson to be a committed Christian-someone who talks openly about his faith."
