Demonizing Palin was just a convenient excuse for 'Rat-addicted Jews to do what was all too comfortable, yet knowingly dangerous: support "Osama" Obama.
I think Palin was a major factor. Before the VP announcement Obama was polling very badly among Jews (for a RAT). Polls were showing him around 55-60% instead of the usual 75-80%.
That shifted dramatically after he chose Palin and the MSM unleashed its lying dogs.
