Game On: Iowa caucuses kick off 2016 presidential election

DES MOINES, Iowa (AP) — After a long year of campaigning, Republican and Democratic presidential candidates face voters for the first time, battling in Iowa Monday for a boost toward the White House — or in many cases, simply a reason to stay in the race.
The contests in both parties were tight heading into the evening caucuses. Among Republicans, billionaire Donald Trump appeared to have a slim edge over Texas Sen. Ted Cruz. Hillary Clinton and Vermont Sen. Bernie Sanders were locked in an unexpectedly close Democratic contest, reviving memories of the former secretary of state's disappointing showing in Iowa eight years ago.
