It’s inherent in the two party system I feel. It’s analogous to that analogy about the two guys on the beach selling ice cream. They start at one end each but in the end they move closer and closer to one another in the middle of the beach or where the most people are. So the Democrats only have to be just “better” than the Republicans to look good and they definitely want to take some of the votes closer to centre.
That being said, they have FAR better stances than the Republicans on many things.
Edit: autocorrect and a typo
It’s normalized already. It’s fucked up.
