Why is the Democratic Party so liberal & leftist leaning in its ideology & how did it get to be that way?

Rationalized impotence, fear, jealousy, and sloth.

It's interesting how you asked a political question under pets/rodents.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
