We conservatives don't need to limit Obama's votes this election because he doesn't have a snowball's chance in hell of getting re-elected. 8 out of 10 that voted for him in 2008 either won't vote this election or will vote republican. The reason being is he is NOT a good president.
Never underestimate the enemy or the power of persuasion over easily deceived and naive people. Tammany Hall politics ruled New York City for decades using the same tactics that Obama's administration and the Obama led Democratic Party is using.
