Politico.com reports that the Obama campaign has booted reporters from right-leaning papers off its campaign plane. Reporters from the New York Post, the Washington Times, and the Dallas Morning News were asked to abandon their seats after covering the campaign for months. Each of these papers endorsed John McCain for president. The Washington Times shot back with this response. "I hope the candidate that promises to unite America isn't using a litmus test to determine who gets to cover his campaign," said Washington Times Executive Editor John Solomon.
