US Presidential race: Last-minute push for Iowa votes

Republican and Democratic presidential hopefuls have toured the length and breadth of Iowa in a frenzied weekend prelude before voters have their first say in the 2016 US presidential race.

The Midwestern state offers only a small contingent of the delegates who will determine the nominees at each party’s national convention in July.

However, today’s caucuses will provide a test of whether the large enthusiastic crowds turning out at rallies for property mogul Donald Trump and Vermont senator Bernie Sanders will turn into actual votes.
