The republicans will have to portray Biden the same way the voters viewed Hillary in 2016 in order to win in 24. Now that they have seen what Biden represents, that should be simple, save the MSM which will portray him as the second coming of Christ. The republicans will have to saturate the airwaves with commercials, because the MSM will not present the facts, describing how much worse off we are now in simple terms, all of the things he is trying to take away from us as a part of the Green New Deal and correlate all of that with their Marxist/Socialist takeover,,, in other words, really wake people up. The Democrats will portray Biden as the savior of the world's clean air, the transgender movement, minority justice, providing safe haven for LGBTQ+ and the man who ended COVID.
It's going to be a tough hill to climb for any Republican, and you can bet it will cost a fortune, but it can be done!
