Trying to trick clueless people, and get the Liberal re-elected
You nailed it with the Ross Perot analogy. He’s trying to slice off a portion of conservative votes by raising the birther issue, knowing that the Republican establishment won’t touch that issue. Even if he only takes 5% of the vote from the GOP, it will be enough to re-elect Obama. We won’t find out until after the election that he’s getting special business considerations from well connected Dems and/or the Fed.
