United States presidential primaries

Bernie Sanders' convincing win in the Nevada caucuses signaled his campaign is gathering strength and reaching voters who had previously eluded him, putting him on a path - for now - toward the Democratic presidential nomination.

Former South Bend, Indiana Mayor Pete Buttigieg and Vermont Sen. Bernie Sanders were in a near-dead heat on Feb. 4 after delayed and incomplete Iowa caucus results showed them holding an early lead with 62 percent of precincts reporting.

"Big WIN for us in Iowa tonight. Thank you!", Donald Trump wrote on Twitter.
Trump campaign used yesterday's contest to test its organizational strength, deploying Cabinet secretaries, top Republican officials and Trump family members to the state, as AP reports.
It's unusual for Iowa to even be holding a GOP contest with an incumbent in the White House.

Problems with a mobile app appeared to force a delay in reporting the results of the Iowa caucuses Feb. 3, leaving the campaigns, voters and the media in election limbo and pressing for an explanation.

The race for the 2016 presidential elections in the U.S. has started, with more than a dozen candidates already expressing their interest in running for their party's presidential nomination.
