Donald Trump Forecasts 'Rough July' as Delegate Battle Continues

He again sounded off against the "rigged system."

Speaking to a crowd of several thousand in Syracuse on Saturday morning, Trump predicted a "rough July," again sounding off against the process from which the party's choose its nominee. He also issued a blunt warning if the "rigged system" wasn't changed.

"You better straighten out the system because the people want their vote," said Trump. "The people want to vote, and they want to be represented properly."

RNC chair Reince Preibus responded to some of Trump's frequent complaints this week, saying it was the responsibility of the campaigns to understand the rules.

Back in New York, where Trump aims to receive 50 percent of the vote in as many congressional districts as possible in order to block his rivals from gaining any delegates, he reminded the crowd he's just like them.

"I love being with you people," he said. "I have that same beautiful little twang as you do."
