In quite a few ways they are similar. Both parties get money from the rich, attack those that have different view points, believe themselves more enlightened than the other, don’t keep most of their promises, lie to get what they want, throw fits when they don’t get what they want, try to divide people on issues, have zealots, and start to do stuff right before elections come up. Ultimately they are the same with minor differences in views that are taken to the extreme by few loud people.
