I'm really not surprised that many Conservatives are 50/50. In these kind of tests I often fall in the middle as well. I only appear very right because I am compelled to bring up the argument against extreme leftists, which multiply like cockroaches these days.
Jon Haidt's study shows that Conservatives are more balanced than Liberals.
Of course, from the POV of a Liberal, anybody who disagrees with them must be an "extreme". But they're so extreme that they can't even recognize the extreme. This is why Obama can't recognize radical Islamist terrorists.
And he can't recognize "illegal" from "legal".
