ABO will not be on the ballot. Romney will. You can only vote for someone. “Against Obama” is not running.
ABO is whoever is on the ballot in December with an R beside their name. If Mittens wins, and he HAS NOT yet, and he is on the ballot in November, and IF the polls show he has zero or little chance to win, then I MIGHT consider writing in Newt or Palin.
Let's put Mao on the ballot versus Obama. Would someone then say Obama is the lesser of two evils and vote for him? Hugo Chavez vs. Obama? Do you always vote for the lesser of two evils not matter how evil the lesser?
Clearly Romney is not Chavez or Mao, but he still believes in socialism, gun control, a liberal court system, and doesn't' believe in the right to life for the unborn. I won't vote for anyone who doesn't respect the rights of people as laid out in the Constitution and Declaration of Independence. Be they Romney or Obama.
