Donald Trump was once best known as the wealthy real estate developer whose empire included the reality television hit, “The Apprentice.” But he and his brand have been transformed by a historic and vitriolic presidential race. Whatever the result on Nov. 8, the Republican nominee’s candidacy will be remembered as a political phenomenon. Trump beat more than a dozen GOP rivals in the primary, boosted by his appeal as an outsider with no government experience with what supporters saw as no-nonsense solutions to keep Americans and their jobs safe. He continues to draw crowds — despite allegations of groping women and a leaked audio in which he makes crude sexual remarks, and without the support of much of the Republican leadership. Trump, 70, a Queens native and Manhattan resident, has ramped up his claims that the system is rigged against him. “Of course, there is large scale voter fraud happening on and before election day. Why do Republican leaders deny what is going on? So naive!” he tweeted last month without offering substantiation. Trump was trailing Democrat and former Secretary of State Hillary Clinton in national polls. The rivals were locked in a tight battle in North Carolina, Ohio and Florida. Domestic interests are at the heart of his platform, as evidenced by his “Make America Great Again” motto, which appears on the red caps of backers throughout his crowds. Trump wants to impose taxes on outsourced jobs and on imported goods, and to renegotiate or withdraw from the North American Free Trade Agreement. The GOP candidate has proposed erecting a wall along the southern U.S. border — and having Mexico foot the bill — to stem the flow of immigrants and drugs arriving illegally. He has also called for a temporary “total and complete” ban on Muslims, though Trump has scaled back the proposed prohibition to target countries with records of terrorism. He has acknowledged not paying up to 18 years’ worth of income taxes after reporting a $916 million loss — citing it as proof of his business savvy. Trump has attacked Clinton as “crooked” and called for her to be jailed.
