This is why Republicans are stupid, a vaccine is a controlled and safe measles exposure with some risk that is 1 in a 100. You are doing the same thing with measles parties but more reckless dangerous levels of infection and putting your kid at risk of death like 1/15 if you send them to the measles parties.
When Sinema left the GOP had to have controlled opposition with Manchin and Fetterman was her replacement.
