Really bad example by Maher.

There are much better examples where the 2 parties are frustratingly aligned to a large extent. For example, datacenters, ICE, and foreign policy. You can find a good number of democrats who are mad about Iran not because it's a dumb war, but because it wasn't done correctly by going through congress.

Both sides are aligned pretty closely in making their donors happy above their voters. That keeps democrats from regulating like they should and it keeps republicans focused on "the enemies within".
