I honestly don't think they are psychotic; I think they represent a certain segment of the evangelical Christian movement, and they believe God will punish us (how could he punish us more?) if we elect a Mormon to the Presidency. By extension, they see any hostility towards a politican as inept as Akin as an attack on "one of theirs", and defend him correspondingly.
You don't have to look too hard around here to find the ideas that the anti-Romney and pro-Akin posters hold in common; for the most part, they are the same. I'd guess that the result that would make them most happy is Akin winning and Romney losing.
So let's give Obama a chance to put infanticide into law.
Oh great! Are these people one cut above the Westboro people?
No, what made Romney happy was McCain/Palin losing. Romney and the liberal wing of the party are out to destroy conservatives and love seeing them lose elections and get trashed in the press. We're simply trying to keep the party a cohesive, functioning unit, which takes one for the team like the Democrats do. It's Romney's RINO wing that is hellbent on driving conservative values out of the party and marginalizing those voices.
