TUCSON: Donald Trump's campaign in Arizona is centered on his hard line against illegal immigration, a stand that supporters embraced in a series of tense rallies ahead of Tuesday's presidential primary in the border state.
"Illegal immigration is gonna stop," Trump said on Saturday in Tucson. "It's dangerous," he said. "Terrible."
Both in Phoenix and Tucson, Trump was introduced by former Arizona Governor Jan Brewer, who pushed tough immigration laws in office, and Joe Arpaio, the Maricopa County sheriff who made his name by chasing down people who are in the country illegally.
The county includes Phoenix and nearly two-thirds of Arizona's population.
Protesters showed up at every event. In Phoenix, they blocked the main road into his outdoor rally for several hours before it started. In Tucson, they interrupted him and some were tossed from the event.
Trump was campaigning in Arizona ahead of Tuesday's primary in which the winner will take all 58 delegates at stake.
Trump's main rivals, Texas Senator Ted Cruz and Ohio Governor John Kasich, are desperately trying to prevent the real estate mogul from accumulating the 1,237 delegates needed to secure the nomination at the party's national convention in July.
They are hoping for a contested convention in which delegates would be free to turn from Trump if he fails to win a majority on the first ballot. Trump has won 678 delegates in contests held thus far, according to a count by The Associated Press. Cruz is in second place with 423 delegates, and Kasich is in third with 143.
His rivals hope to offset a likely Trump win in Arizona on Tuesday with a strong showing in the Utah caucuses. Limited polling shows Cruz leading in the state where Mormons account for two-thirds of the state's 3 million residents.
Mitt Romney, the 2012 Republican presidential nominee and the Mormon faith's most visible member, said he intends to vote for Cruz in the caucuses, but stopped short of endorsing the Texas senator, an uncompromising conservative.
However, Utah's delegates will be distributed proportionally based on the percentage of votes -- unless a candidate gets more than 50 per cent, which would give that person all 40 delegates.
In Arizona, Trump treated the latest protests with a mix of pacifist rhetoric and a mocking tone. "We love our protesters, don't we?" he asked. As security removed one or more, he said: "We want to do it with love," then added bitingly, "Get 'em outta here."
