Trump’s surge confounds rivals, makes him betting favourite

WASHINGTON — Donald Trump inched closer to the US Republican presidential nomination as his odds shot to a record high on global betting websites on Wednesday and he won his first endorsement from a member of Congress.

The outspoken businessman easily won the Nevada caucuses on Tuesday, giving him his third win in four early nominating contests and pressuring Republican rivals to come up with a way to stop a candidate who only last year was not seen as a serious contender for the November 8 presidential election.

The real estate billionaire swept Nevada by a margin of 22 percentage points, winning 45.9 per cent of the vote.

It was the high point so far of an unorthodox campaign during which Trump has fought with Pope Francis, called for a temporary ban on Muslims entering the United States and promised to build a wall on the US-Mexican border to prevent illegal immigration.

Trump's Nevada win is likely to further frustrate Republican establishment figures who, less than a month ago, were hoping his campaign as a political outsider was stalled after he lost the opening nominating contest in Iowa to Ted Cruz, a US senator from Texas.

In his victory speech in Nevada, the former reality TV show host courted his base of blue-collar workers.

"I love the poorly educated," he said, mentioning several demographic groups among whom he said he was winning.

By Wednesday, that phrase was being widely discussed online, with some finding it funny and others arguing it was a welcome, nonjudgemental embrace of a constituency that other politicians might speak of only as a problem to be fixed.

Trump's nearest rivals, Cruz and Marco Rubio, a US senator from Florida, have frequently attacked each other, clearing a path for Trump to the Republican nomination that includes primary elections in a slew of southern states on March 1, known as Super Tuesday.

"These guys have to figure out how to turn their fire on Trump," said Ford O'Connell, a Republican strategist in Washington. Absent that, he said: "Which one is going to get out of this field?"

Rubio and Cruz have struggled to match the popularity of Trump, who is more ready than the two senators to deviate from the tenets of the Republican Party's brand of conservatism, including free trade and supply-side economics.

Congressional endorsement

On Wednesday, Chris Collins, a Republican congressman from Trump's home state of New York, became the first national lawmaker to endorse Trump, saying in a statement "it's time to say no to professional politicians and yes to someone who has created jobs and grown a business".

Speaking earlier on Wednesday, Trump called endorsements a "waste of time" that "mean very little" in an ABC interview.

Betting venues in Britain, Ireland and New Zealand show the online wagering community coalescing around Trump, once considered an interloper, attracting long-shot odds of 200/1.

Odds for Trump becoming the Republican candidate for November have tightened all the way to a-half in some cases.

While more than 1,200 delegates are needed to secure the Republican presidential nomination, Trump has built a formidable head start over Rubio, who came in second in Nevada with 23.9 per cent, and Cruz with 21.4 per cent.

Opinion polls show Trump ahead in most Super Tuesday states, placing further pressure on Cruz and Rubio, who will have what may be their last chance to change course when the Republican candidates meet for a televised debate on Thursday night.

The primary election next Tuesday in Cruz's home state of Texas is looming as a make-or-break moment for him after Trump's growing success among the senator's core base of evangelicals and other conservative supporters.
