Biden just started his office late last year and it’s too early for this kind of prediction since we don’t know who will represent both parties and seriously, I’m still looking for the early projects of Biden and what he has done for over a months now. Mike Pence might be one of the option, we’ll see about this in the next 3 years, too early for this.
Mike Pence is one of the front runners for GOP nomination. But as of now, it is not clear whether Trump will run again or not. Opinion polls indicate that anywhere from 60% to 80% of the GOP voters would prefer him in the primaries, if he announces his candidacy. If Trump wins the GOP nomination, then 2024 will witness a direct battle between the extreme-right and extreme-left camps (Trump vs Kamala). If GOP nominates someone with moderate views, then that candidate will be able to win most of the independent voters, who don't want to support Kamala. But in case of Trump, that is not going to happen.
