GREEN BAY, Wisconsin, April 20 (Reuters) - By the time Donald Trump took to the stage for his rally in Green Bay, Wisconsin, some of his most ardent supporters had spent the night in their cars amid frigid temperatures to see the man they hope to once again elect as president.
As Lee Greenwood's "God Bless the U.S.A." pumped from the speakers inside the convention center, the Republican former president-turned-candidate waved, swayed, clapped and blew kisses.
"Trump, Trump, Trump," some in the crowd of 3,200 people chanted. A young couple held their baby aloft. A few people got teary.
Trump's rallies are a defining feature of his presidential campaigns: all-day spectacles blending evangelical revivalist meeting and carnival, designed to deliver an emotional experience to his base and bring new backers into the fold, his campaign said.
