Makes sense because the POTUS will be a Marxist who supports nationalized healthcare no matter who wins, but if Romney wins the election, GOP too will end up with the Karl Rove gang which consists of supporters of nationalized healthcare and baby-killing. Instead of losing both the presidency and the GOP to the baby-killers who support a nationalized healthcare system, many patriots want to at least save the GOP.
I hope this answers your question.
Excellently well said, JW.
