They used to have that guy Joe Manchin. He wasn't too stupid.
Look, when you're broke, lack ambition, your parents cut you off, you wasted your parent's money or worse student loans on some social studies degree - we know 1) you're stupid, 2) you are a Communist and 3) you will be looking for a government job if you want to survive. So, yes, Democrats really are that stupid, and only stupid people can be candidates in that party.
