I was on to this before, and it bears repeating when timely.
Maher’s underlying observation is derived from an exercise in self adulatory projection that’s common to the left. Maher thinks atheists are hip and smart, and those with faith dumb and square. Maher is hip and smart, just ask him, and he voted for Obama. He wouldn’t vote for someone dumb and square. Ergo, Obama must be hip and smart and an atheist.
Not that Maher’s conclusion is wrong, by the way. At this point the superficial faith of Democrat candidates is probably in most cases a ruse conducted for the sake of swinging some rube moderates. The base tolerates this, but it’s like gay marriage was. If any of these guys, including the President, had some appearance of sincere, authentic faith, they probably couldn’t win whatever nomination they sought.
