There were also new signs of diversity on the Democratic side.
Trump has waded into Florida's hotly contested Republican gubernatorial primary, endorsing conservative US Representative Ron DeSantis over Adam Putnam, the state agriculture commissioner and a former US congressman.
After yesterday's primaries, only five states remain to pick candidates before full attention turns to the November election, when all 435 House seats, 35 Senate seats and 36 governors' offices will be at stake. DeSantis has leaned heavily on his allegiance to Trump, even running an ad where he's "building a wall" and reading The Art of the Deal to his kids.

Four others in Florida also won Tuesday. The Democrats' total was about 33 percent of Hillary Clinton's 2016 turnout. Republican Gov. Doug Ducey could also be vulnerable this fall. DeSantis has the endorsement of President Trump.
There was less drama on the Senate side in battleground Florida, but the stage is now set for what will likely be the nation's most expensive midterm contest.
McSally and Sinema will face off in the general election for Jeff Flake's Senate seat on November 6.
Scott, an independently wealthy businessman, has already spent more than $27 million on the race compared to Nelson's $6 million.
