"Are all liberals 5 year olds mentally?"
As much as I'd like to say yes, I'm going to have to say no. They're smart, but maybe only book smart (and it's not a very good book...) I think they may very well be immature when it comes to reality. They're well intended people who think their crazy policies help people, with no regard to destroying the country those people live in. And clearly they have trouble thinking for themselves. Without CNN, MSDNC, Washington Compost, etc., telling them what they know, they'd be in real trouble.
