Democrat Bernie Sanders won the parliamentary groups in Maine, defeating former Secretary of State Hillary Clinton in the race for the Democratic nomination.
With 91% of the vote counted, Vermont Sen. Bernie Sanders voted 64%, while former Hillary Clinton had 36%.
In the Republican race, Marco Rubio easily won the championship in Puerto Rico, defeating Donald Trump.
Hillary Clinton and Donald Trump remain the main leaders in the nomination campaigns.
On March 6, Hillary Clinton and Bernie Sanders clashed over a number of issues in a CNN debate in Flint, Michigan.
They traded on economic and trade charges, with Hillary Clinton saying her rival voted against saving the US auto industry in 2009.
“I went with them. You are not. If everyone had voted like him [Bernie Sanders] indeed, I believe that the car industry would collapse by taking four million jobs with it, “ Hillary Clinton said.
Bernie Sanders countered by saying: “I would be damned if the working people in this country had to save the Wall Street crooks.”
He described the measures taken at the time as “the Wall Street rescue program, where some of your [Hillary Clinton’s] friends destroyed this economy. “
During the March 5 vote, Bernie Sanders took two states – Kansas and Nebraska, but Hillary Clinton retained her status as a Democratic candidate after a major victory in Louisiana.
While the victory in Puerto Rico will intensify the campaign of Florida Senator Marco Rubio, it sent only 23 delegates to the Republican Convention, which nominates a candidate for president.
Republican Hopes need the votes of 1,237 delegates to get a vote in the right presidential race.
Marco Rubio is still well behind Donald Trump and Texas Sen. Ted Cruz.
Speaking after victories at the Republican Club in Kentucky and the primary election in Louisiana on Saturday, Donald Trump told a news conference: “I’d love to fight Ted Cruz one-on-one.”
“Marco Rubio had a very bad night and I personally urge him to drop out of the race. I think it’s time to drop out of the race. I really think so. “
Ted Cruz, who won the Republican Party in Kansas and Maine, said he believed “as long as the field remains divided, it gives Donald an advantage.”
