Then they should put a D beside their name and stop lying to people about their political affiliation because I'll guarantee you that a Republican might vote libertarian but they would literally never vote for Kamala Harris.
To pretend that turning our back on Israel when they are in a war, wanting to try and contravene the supreme court and federalize pro-partial birth abortion laws, pro- who cares about women laws and attempt to change title 9 forcing women to compete against biological men, open borders, horrible economic policies and more are just fine policies for a Republican is a lie on it's face.
Republicans are pro- economic growth, pro states rights on abortion laws, we stand by our allies when they are ruthlessly attacked by terrorists, and we defend our nation from foreign invaders so that Americans are not unnecessarily burdened or harmed etc etc etc.
Very different policy objectives and a Republican isn't signing up onto the Democrats platform.
