Hillary Clinton and Donald Trump now plunge into a six-month battle for the presidency. While Clinton heads into the general election with significant advantages with minority voters and women, Democrats have vowed to not underestimate Trump as his Republican rivals did for too long.

Front-runners Donald Trump and Hillary Clinton swept to resounding victories in the New York primary election, with Trump bouncing back from a difficult stretch in his Republican campaign and Clinton pushing tantalizingly close to locking up the Democratic nomination.

While both front-runners scored victories in the night's biggest prize of Arizona, Democratic challenger Bernie Sanders won caucuses in Utah and Idaho and Republican Ted Cruz claimed his party's caucuses in Utah.

Defying the polls again, Ted Cruz claimed his first victory in the GOP primaries as Donald Trump was handed a loss and Marco Rubio came in with a stronger-than-expected third place.
