I think the whole group think mentality is much more common with those that are college educated or more so those that lived the "college lifestyle". It is very common that many idealistic people assume that voting Democrat is a vote for saving children, stopping wars and some gateway to an enlightened society and they vote blindly under that assumption.

Voting partisan these days is a sign of lapping up every last drop of party propaganda they serve.

Real educated people vote based on facts and research, not washing out to one side or the other.
