Here’s what I can tell you. Being a republican is a way of life for many folks. It’s an identity, often tied in with their faith. This situation is not going to change many votes to the Harris column.
Imagine if Trump, while he was president, had an effective response to Covid. Would you have changed your vote to him in 2020? Prob not. You’d say, yeah, I give him props for doing his job, but can’t wait to get rid of him in November. Same deal here — and that’s only IF people can see past the disinformation machine and give credit to Cooper and Biden.
