Since President Trump is in his second-and-last constitutionally permitted term, it isn't too early to begin thinking about who will run in 2028. A firm named Political Polls surveyed both Democrats and Republicans about their support for the people who've been talked about as contenders. Breitbart's John Nolte has the findings:
The Democrats are butt-hurt, see their 'preferiti' with the percentage favoring each.
> Buttigieg 16%
> Harris 13%
> Newsom 12%
> Shapiro 7%
> AOC 7%
> Sanders 5%
I summed those percentages and they total 60%. Something like a third don't like any of these, and might stay home. Meanwhile the leading Republicans are in better shape, see the percentage favoring each.
> Vance 46%
> Rubio 12%.
> DeSantis 9%
Nolte concludes a Republican would be favored to win if you were betting now, he dreams of a Vance/Rubio ticket.
