First off, you do not know if he will pick someone that mirrors Sarah or not.
Secondly, Obama's left-wing, progressive liberal policies & actions treble that of Romney, maybe even quadruple. On top of that he is deadly serious about destroying this country as evidenced by the multitude of left-wing uber radicals in positions of very high government positions. Be it the courts (Supreme & Federal), high & low level government bureaucrats, or Czars that are accountable to no one.
Your argument is weak, even if factually correct. Weak because it does not take the full equation into account..
How anyone can watch the bast$rd in the White House spiking the football in AFG today, taking credit for things that our soldiers did, and not want to do everything they can to get him out, I will never know.
