Washington:
US presidential candidate Ted Cruz won the backing of former rival Jeb Bush on Wednesday as prominent Republicans overcome their aversion to the conservative senator to try to force a standoff with insurgent Donald Trump at their party's convention in July.
The endorsement by Bush, part of a Republican dynasty, is the latest sign of how keen the party's establishment is to stop Trump, fearing that his rhetoric on illegal immigration and national security will cost the party votes at the November 8 presidential election.
Cruz, a US senator from Texas, is a staunch social conservative and a divisive figure in the party due to his willingness to criticize the leadership and his prominent role in bringing about a 2013 government shutdown.
But he is still seen by party grandees and many Republicans in Congress as preferable to Trump, a real-estate billionaire viewed as straying even further from party orthodoxy.
"Republicans across the spectrum are realizing that to nominate Donald Trump brings chaos to our party and potentially to our country," U.S. Representative Trent Franks of Arizona told Reuters, "and that any differences they might have had with Ted Cruz are far less important than the danger of nominating Mr Trump."
Cruz won the Republican caucuses in Utah on Tuesday but time is running out for him to defeat Trump before the Republican convention in July, and for Republican establishment figures to reassert control of a party that is being wrested away from it by rank-and-file voters.
Cruz looked on track to win all of the 40 Republican delegates from Utah, although Trump won the 58 delegates up for grabs in Arizona, partly due to his tough message on illegal immigration.
After Tuesday, Trump had 738 of the 1,237 delegates needed to win the nomination, according to The New York Times. Cruz had 463.
On the Democratic side, US Senator Bernie Sanders of Vermont won in two out of three states that voted for the party's nominee on Tuesday, but this made only a small dent in the lead held by Hillary Clinton, a former secretary of state, who won Arizona.
The Bush endorsement put pressure on Ohio Governor John Kasich, who is struggling in third place in the Republican race, to drop out.
"Kasich was viewed as the only establishment candidate left," said US Representative Matt Salmon of Arizona, a Cruz supporter. "With the quintessential establishment candidate now endorsing Cruz, it makes Kasich irrelevant."
People in Kasich's campaign suggested the candidate was paying no more attention to party elites than voters were, saying he planned to survive to the convention and wrestle the nomination there.
In interviews, some Republican lawmakers and wealthy party donors who had supported Bush thought the endorsement would do little to dampen voters' enthusiasm for Trump.
"I'm surprised," Gaylord Hughey, a prominent party fundraiser from Texas who worked on Bush's finance team until the campaign ended last month, said, adding that donors were given no notice of the endorsement.
US Representative John Duncan of Tennessee said the endorsement would "make a miniscule difference at most."
CRUZ UNDAUNTED
Cruz remains undaunted, and added Bush's name to a list of prominent Republicans who had belatedly rallied to his cause, including Mitt Romney, the party's unsuccessful 2012 candidate.
"Across the spectrum Republicans are uniting," he told the crowd at a New York City campaign event. "Independents are uniting. Libertarians are uniting. Democrats who are tired of what we're doing are uniting."
But Cruz is far from united with his rival Trump, and their feud spilled on to social media in a spat drawing in the candidates' wives.
Make America Awesome, an anti-Trump political group, featured a scantily clad photo of Trump's wife Melania, a former model, in an ad. Trump hit back on Twitter, saying "Be careful, Lyin' Ted, or I will spill the beans on your wife!"
Cruz on Wednesday said he considered Trump's words a threat and said Trump was "a bully."
