Romney doesn't scare me because his presidency would be the same as Obama's. I DON'T want another Obama term, but I know what it is like at least.
Gingrich is on a completely different level of scary. He is smart evil. If he won we would know what it is like to have a super villian as president and it wouldn't be pretty.
Santorum scares me, but not as much because his says way too many idiotic things to ever get enough support to enter the white house. He is more like stupid evil, although his presidency might be scarier than a gingrich presidency. We might have a theocracy under him and I'd end up hanging out with you guys in some re-education camp. He is basically an admitted fascist. But unlike Gingrich and Romney supporting fascist policies to help special interests and their own personal lust for power, Santorum seems to be more of a true believer when it comes to fascism.
I generally long considered Santorum to be the scariest in the sense of if he was actually president. As a Pennsylvanian I just figured people wouldn't fall for his idiocy and long considered him to have absolutely no shot of doing well considering his insane views. I guess I was wrong. Those poor, poor souls that are supporting him...
If things were going to be the way they have always been, I'd say you were right.
Should the world go the way many smart people say it will, it is URGENT that we have a leader in charge who will NOT sign bills that give away your right to demand a search warrant, that would NEVER detain you without cause and that WOULD FIGHT for your right to free speech...NOT GIVE IT AWAY.
Liberties given away, you NEVER get back.
