Democrats will shit on each other and hang each other out to dry and abandon someone over the smallest inconvenience in their ideology.
Republicans will protect even grossly incompetent assholes who they disagree with in the name of party unity. (Exception: the “RINO” argument. If the overall Republican party believes someone is a RINO, they will shit on them and run them out of the party. This is the only sin that is worthy of expulsion inside of the Republican party).
