The problem with the GOP is this country gets more disinterested and ignorant of politics every day, relying on "news" sources like Tucker Carlson, who distorts the truth to make Republican chicanery seem normal and in their best interest. With the onset of AI and "deep fakes", more and more of these people will be fooled like never before, and continue to put their faith in charlatans like Trump.
And that's what people want, they want to yell, scream, and have someone express their anger for them, and no one can do it like a crazy person can. I don't think the base is interested in "fiscal responsibility".
