Since My Neck My Back came out, Republicans have become less a party about policies, and more a party about "fuck those guys over there." There was always moral panic as an important part of that party, but right now Joe Biden's policies are popular, even with many Republicans. Obamacare is popular! They have literally no substance to run on and they can't just sit back and attack the Democrats because people like what they are doing, so the only thing left is culture war.
Hence, they spent the last month on WAP, a song that came out last year, and Dr. Suess, a guy that died decades ago. Not like anything else important is happening right now.
