Franklin Graham, the son of...

...the famous evangelist Billy Graham, and a modern-day Elmer Gantry in his own right, said on MSNBC's "Morning Joe" yesterday: 

...that he was not sure if President Obama was a true Christian and that he could not definitively say that the president was not a Muslim. 

You can read the rest of it here; it's too discouraging to spend a lot of time on. 

But the question I have is, why on earth would Joe Scarborough have a crackpot like Graham on his show? Does he think that Graham adds to the national dialogue?
