I don't know a single person who's "blindly loyal" to Biden. Most people I know think he's overall pretty reasonable and certainly disagree with him on some things. I also know quite a few Trump voters, as I do live in Texas, and those people are beyond rationality at this point. Trying to have a conversation about an issue is utterly useless, because all they know how to do is restate whatever line they've been fed by whatever conservative media they watch.
My point is this tweet is absolutely bullshit
