On tonight's Real Time with Bill Maher, Maher ended his show with a short rant about the bubbles that both sides of the political aisle live in. The Conservative bubble is well established, but Maher believes that the Liberals live in one too, one where they don't think President Obama can lose on account of what jokes Romney and Santorum are. As Maher reminds us, there was another joke candidate no one thought had a chance a few years ago: George W. Bush.
