Vermont voters made history on Tuesday as Christine Hallquist, a transgender woman, won the Democratic primary for governor.

Hallquist, who will now face Vermont Republican Gov. Phil Scott in the general election, becomes the first openly transgender person to ever win a major party's nomination for governor in U.S. history. If she wins in November, she'd be the nation's first transgender governor.

Hallquist, a former energy company executive, defeated three other candidates to win the Democratic nomination, but Scott won't be easy to beat, even in solidly blue Vermont.

The GOP governor had enjoyed high approval ratings and the Cook Political Report still rates the race as solid Republican. Scott did see his approval ratings drop, though, when he signed a sweeping package of gun control measures — though that mainly came from within his own party, and is probably one reason he was only getting about two-third of the vote in the GOP primary. Polls show Scott still has good numbers among Democratic voters, though.

Hallquist easily defeated three Democratic opponents, including 14-year-old Ethan Sonneborn. Even though he wasn't old enough to vote for himself, Sonneborn ran for governor thanks a quirk in the state constitution that didn't set age requirements for the governor.

Sen. Bernie Sanders also won the Democratic nomination for Senate, though the possible 2020 presidential hopeful plans to decline it again to run as an independent.
