The extreme factions of the right are a very small portion of the electorate. They generally don't decide elections beyond the primaries and generally turn out in favor of the right regardless.

Dems lean more on moderates/independents. Trump won because he persuaded that group, particularly the young men.

25-33% of the electorate is no small fraction. There's a group of people who have been consistently supportive of this government's policies since 2016. Take any policy survey, and the fraction that supports the right-wing side of action always amounts to a consistent 25-33% of the votes.
