US primaries: Republican Marco Rubio registers his first win in Minnesota

US Republican presidential contender Marco Rubio on Wednesday registered his first victory in the party's primaries as he won in Minnesota, giving a much needed boost to his campaign.

Rubio's win in Minnesota and a close second position in Virginia will be disappointment for Ted Cruz, who after two victories in Texas and Oklahoma had called him and other candidates to drop out of the race for him to defeat the Republican front-runner Donald Trump.

The Florida Senator insisted that he is in the race to the White House and is the best Republican to defeat Trump in this Republican presidential elections. During a speech in Miami, Rubio said his aggressive campaign against Trump is now yielding results.

"Five days ago, we began to explain to the American people that Donald Trump is a con artist," he said. "In just five days, we have seen the impact it is having all across the country. We are seeing in state after state, he (Trump) loves to talk about polls, we are seeing in state after state his numbers coming down, our numbers going up," Rubio said.

"Two weeks from tonight, right here in Florida, we are going to send a message loud and clear," he said exuding confidence that he would win the Florida primary in two weeks from now. "We are going to send the message that the party of Lincoln and Reagan, and the presidency of the United States will never be held by a con artist," he said.

"We will not allow the next President of the US to be a socialist like Bernie Sanders. And we will not allow the next President of the US to be someone under FBI investigation like Hillary Clinton," he added. "I will unite this party, and we will grow it, and we will win in November, and we will turn this country around. The stakes are too high, and we will do whatever it takes," he said.

"We believe in free enterprise. We believe in a strong national defense. We believe in limited government. We believe in the Constitution of the US," he said. "We believe the world is a better place when America is the strongest country on earth. And we know that America is strongest when it stands with its allies, allies like Israel.

We will always be on their side. We stand for freedom in Cuba, in Venezuela, in Nicaragua. These things are not negotiable," Rubio said. "When Trump was asked about whether he would side with Israel, he said he's not taking sides he wants to be impartial. When I'm president of the US , we are taking sides we are on Israel's side," he added.
