General election matchup

Gavin Newsom vs Marco Rubio: 2028

Gavin Newsom (Democratic) and Marco Rubio (Republican) are two of the most-discussed names for 2028 - but they have never faced each other, and no 2028 nominee has been chosen. There are essentially no head-to-head 2028 general-election polls this far out, so the honest answer to "who would win" is: it is far too early to know. Here is how they actually compare.
