Republican front-runner Donald Trump swaggered into Arizona again Saturday, repeating his promises to build a border wall, renegotiate U.S. trade deals and generally "make America great again."

Wearing a blue jacket and red golf hat as he addressed the thousands gathered in Fountain Hills Park, Trump made a final pitch ahead of Arizona's presidential primary on Tuesday.

"Go out on Tuesday and vote. I will never let you down," he told the crowd, which had waited for hours in warm sunshine. He referred to them as a "loud, noisy majority."

Trump was joined on stage by Sheriff Joe Arpaio, former Gov. Jan Brewer and Treasurer Jeff DeWit. Former Arizona lawmaker and 9/11 "truther" Karen Johnson prayed to open the event.

Trump's arrival was delayed by protesters who blockaded one of the main traffic arteries into Fountain Hills. And he was in a fighting mood as he deployed his signature name-calling.
