They don’t care about looking like absolute clowns. They only care about appeasing Trump and MAGA base. Both say that Biden needs to be impeached. They don’t care why - just impeach him. If anyone says they look like clowns, they’ll just call those people “woke liberal elites working for Soros globalists” or “RINOs” (depending on whether they are Democrats or Republicans).
Then, if they lose their elections due to a blue wave, they’ll parrot Trump, claim voter fraud, and demand that they be installed into office because they won when you subtract all the “fraudulent” (read: Democratic) votes.
