In Saturday balloting, Clinton wins islands caucus, Rubio wins in D.C., Cruz wins majority of Wyo. delegates at stake

Democrats and Republicans are balloting Saturday in a mix of primaries and caucuses in Wyoming, the District of Columbia and a U.S territory.

The Associated Press declared Sen. Marco Rubio the winner of caucuses in heavily Democratic Washington, D.C. The turnout of just several thousand voters is so small that balloting has been limited to one downtown hotel. However, 19 delegates were stake.

It's the third presidential contest victory for the Florida senator. Earlier this month, Rubio won the GOP caucuses in Minnesota and the party's primary in Puerto Rico.

Rubio picked up 10 delegates with his Saturday caucus win in the nation's capital. Runner-up John Kasich was just 50 votes behind Rubio, and the Ohio governor will get nine delegates.

None of the other candidates in the race won enough votes to earn any delegates.

However, 2016 GOP frontrunner and anti-establishment candidate Donald Trump last week won the D.C. Republican Party’s straw poll.

Kasich on Saturday delivered his harshest criticism yet of Trump, saying at a rally in Heath, Ohio, that he has "had it" with the "toxic" nature of Trump’s campaign.

"Why don't we talk about our vision?" Kasich asked attendees at the town-hall style event. "Let's not try to separate people from one another."

Democratic frontrunner Hillary Clinton on Saturday won the party’s caucus in the Northern Mariana Islands, the U.S. territory in the Pacific Ocean, near Guam.

Clinton received 54 percent of 189 votes cast to earn four of the six delegates at stake. Rival Vermont Sen. Bernie Sanders won the two remaining delegates. Results are expected later on the GOP side from Guam.

In Wyoming, Republicans held caucuses to select the state's first 12 presidential delegates. They will choose 14 more delegates at their state convention in mid-April. The other three are the state GOP chairman, national committeeman and national committeewoman.

Texas GOP Sen. Ted Cruz was the only active Republican candidate to have campaigned in the state, which will bring a total of 29 delegates to the national convention this summer.

Cruz won most of the delegates at stake in Saturday's Republican county conventions in Wyoming.

Cruz won nine of the 12 delegates that were up for grabs. Florida Sen. Marco Rubio and billionaire businessman Donald Trump won one apiece. One delegate was uncommitted.

The Associated Press is not declaring a winner in Wyoming on Saturday because another 14 of the state's delegates will be awarded at the party's state convention on April 16.

The candidates this weekend are largely looking ahead to the five primaries on Tuesday, including the essentially winners-take-all contests in Ohio and Florida that will likely be make-or-break for Kasich and Rubio.

And big wins by Trump, who leads Rubio in Florida, could be decisive in his march to the party nomination. Trump has a single-digit lead over Kasich in Ohio, according to the RealClearPolitics poll average.

The other states holding primaries Tuesday are Missouri, North Carolina and Illinois.
