I mean it’s been working for Trump thus far, and DeSantis has been chasing that dragon pretty much from the moment he declared.
Short of Biden becoming unfit for office I just don’t see this happening. He has a record to be proud of, Democrats just suck at telling people about it and the media is so busy having their tails wagged by Trump that they don’t bother reporting on it. Any serious contender right now on the D side will only guarantee an R wins in 2024.
