‘Acting too presidential would be boring as hell’

Donald Trump has said acting too presidential would be "boring as hell". The New York businessman, the frontrunner in the race to become the Republican presidential candidate in the US election, has often been criticised for his tone on the campaign trail.

But at a rally in Superior, Wisconsin, the 69-year-old said his unorthodox style was more entertaining. "I can be presidential, but if I was presidential I would only have – about 20 per cent of you would be here because it would be boring as hell, I will say," he told voters at an open airplane hangar, according to Politico.

Voters in the state of Wisconsin cast ballots yesterday in US presidential primary races in which challengers to Republican Trump and Democrat Hillary Clinton seem poised to win.

The potentially pivotal contest is the first after a 10-day lull in the process that determines the parties' nominees for the November general election. Voting began at 7:00 am.

Trump's main rival Senator Ted Cruz is eyeing the Badger State as a crucial firewall against the celebrity billionaire's march to an outright nomination victory. Like Trump, Clinton risks losing Wisconsin, where she faces a surging Bernie Sanders who has won five of the last six contests, reports AFP.

But April could ultimately prove a sunny month for the former secretary of state. She leads Sanders by double digits in New York, which votes April 19, and Pennsylvania, which casts ballots a week later. Trump also leads handily in those states. Wisconsin, the birthplace of the Republican Party, is seen as Ground Zero for the anti-Trump movement. Halting him there would bolster Cruz, the 45-year-old conservative senator from Texas.
