[00:10.96]Political experts say the clear win in Nevada [00:15.28]was a big relief for Clinton and her supporters. [00:20.08]They say Sanders must prove he can win more than the youth vote, [00:25.20]and in states more diverse than New Hampshire. [00:29.32]Sanders said he believes that when Democrats hold their convention in Philadelphia in July, [00:37.12]voters will see "one of the great political upsets in the history of the United States." [00:44.16]Also on Saturday, Donald Trump won the Republican primary in South Carolina. [00:51.96]Marco Rubio and Ted Cruz tied for second. [00:57.24]Trump's victory in the New Hampshire primary last week [01:01.16]and his win Saturday strengthen his place as Republican front-runner. [01:07.20]Trump repeated parts of his campaign speech, [01:10.36]saying the United States will start "winning again" if he becomes president. [01:16.52]He said he will make Mexico pay for a wall along the U.S. southern border. [01:23.12]He said he will challenge China on its trade surplus. [01:28.28]Nevada holds its Republican primary on February 23. [01:34.40]Many states will hold primaries on March 1, [01:38.64]a day known as Super Tuesday. [01:42.72]Super Tuesday usually shows who will likely win the party nomination [01:48.80]and compete for president of the United States. [01:53.04]Former Florida governor Jeb Bush told a crowd in South Carolina [01:57.96]that he was ending his campaign for the presidency. [02:02.32]At the beginning of the presidential race, [02:05.08]many believed Bush would be the Republican nominee. [02:09.60]I'm Jonathan Evans.
