Civics: word for a representative's constituent who voted or will vote for them

In the U.S. as an example, a senator represents constituents — the people in her area of representation. What’s a word or short term for those constituents who voted for her?

As a more concrete example, what political term could we use to describe the Californians who voted for and elected Nanci Pelosi, the Floridians who voted for and elected Marco Rubio, or the Connecticuters who voted for and elected Richard Blumenthal?

I’d be quite happy if such a term also included people who currently intended to vote in the next election for the politician in question.
