NEW YORK — Republican Donald Trump declared it’s “great to be home” at a massive rally in the New York City suburbs Wednesday, shrugging off a defeat in Wisconsin a day earlier and instead, predicting victory in his delegate-rich home state. “I love these people. These are my people,” he said to thunderous cheers. Dozens of police officers amassed outside the soundstage venue on Long Island as protesters chanted “your hats are made in China” and “dump Trump.” Trump supporters retaliated, declaring “socialism sucks!” and “leave this country!” The rally comes as the GOP front-runner signaled a shift toward “more meat on the bone” in his policy speeches amid new signs of campaign discord after his stinging Wisconsin loss to rival Ted Cruz emboldened his critics and pushed the GOP closer to its first contested national convention in four decades. Former gubernatorial candidate Carl Paladino, one of Trump’s state co-chairs, said the campaign received 18,000 requests for Wednesday’s event, although the venue holds just 3,000 people. Said Paladino, a Buffalo-based businessman: “We’ve seen people just coming up saying, ‘Where has he been?’ Thank God he’s here.” As for possible friction in the campaign, Paladino said he’s had no problems with Trump’s campaign manager. “They do have a small staff — probably smaller than they should have — but these guys work 24/7,” he said.
