Florida Rep. Ron DeSantis has won the state's Republican nomination for governor, getting a boost by President Trump in his primary over establishment-backed Adam Putnam, the state's agriculture commissioner.

With nearly half of the vote counted when the Associated Press called the race, DeSantis was leading Putnam by nearly 20 points.

DeSantis tied himself closely to Trump in the primary, and it paid off. In one memorable ad, DeSantis showed himself with his children, teaching them to "build the wall" with blocks and reading them the president's famous book, The Art of the Deal.

Trump held a rally in the state to help the Republican congressman and sent out plenty of tweets praising DeSantis, who's been one of his most vocal allies in Congress.

Putnam, a former congressman who was once seen as a rising star in the GOP, criticized DeSantis as nothing more than a puppet of the president and said he was out of touch with Florida-specific issues. But, as it has time and again in Republican primaries this year, that tactic fell short.

DeSantis's victory is yet another example of Trump's ability to lift candidates to victory in GOP primaries. One notable exception where Trump couldn't do that was last week in Wyoming's gubernatorial primary, where Republican megadonor Foster Friess fell short. But in other races in South Carolina, New York and more, he's shown an ability to move voters to candidates who side with him and against candidates who don't, even incumbents.

But the more conservative DeSantis could give Democrats a chance to take back the governor's mansion for the first time in two decades.

The Democratic primary is currently close between former Rep. Gwen Graham — a centrist and daughter of former governor and Sen. Bob Graham, who's the preferred candidate of the national party — and Tallahassee Mayor Andrew Gillum, who is the progressive favorite and has the backing of Vermont Sen. Bernie Sanders.

Florida will also be home to one of the top Senate contests this cycle. Current Republican Gov. Rick Scott easily defeated a nominal challenger to win the GOP nomination. Now, he'll face Democratic Sen. Bill Nelson this fall in one of Republicans' best pick up opportunities.
