The US presidential circus is barnstorming New York, where adoptive daughter Hillary Clinton and native-born sons Donald Trump and Bernie Sanders are battling to win the state’s most important primary in decades, reports AFP from New York. Despite being the media and financial capital of America, New York is typically a sideshow in presidential elections, an overwhelmingly blue state whose primary typically comes too late to make a difference. But with Republicans potentially facing a contested election and Clinton locked into a tighter race than she imagined, the 247 Democrat and 95 Republican delegates up for grabs could prove decisive. This year, New Yorkers also have the unique choice of three candidates who consider the state their home: celebrity Manhattan tycoon Trump, Brooklyn-born Sanders and two-time senator Clinton. With three weeks to go, polls give Clinton and Trump a thumping advantage. Clinton leads Sanders 54 to 42 per cent, according to the latest Quinnipiac University survey.
