Feb. 1, thousands of Iowa residents gathered at various caucus sites, discussing and ultimately choosing Texas Senator Ted Cruz as their presidential nominee, and leaving a close, undecided race between Vermont Senator Bernie Sanders, and former Secretary of State Hillary Clinton.

Shortly before the caucus began, Huffpost pollster showed a tight gap in popularity amongst the two leading Democratic candidates. Clinton was shown at 47.7% popularity, while Senator Bernie Sanders trailed shortly behind at 44.6%.

The difference between Republican candidates, however, was much more vast. Republican front runner Donald Trump was shown at 38.7% popularity, while the next candidate, Cruz, landed farther behind at 15%.

This small gap between Democratic candidates reigned true as of 6 a.m, Feb 2. With 99% of the votes counted, Clinton prevailed by a meager .4%, but unlike earlier predictions, Trump was behind with no chance of recovery by 3.4%.

Ultimately, the selection of the Democratic nominee depends largely upon voter turnout. Sanders, whose following consists largely of young adults,will be more likely to overcome Clinton’s slight edge with the participation of new voters and millennials, whereas Clinton’s campaign depends more largely upon experienced voters and women.

Cruz, a candidate who held similar values to the Iowan voters, benefited for this reason.

With the completion of the caucus, both former Governor of Arkansas Mike Huckabee and former Governor of Maryland Martin O’Malley have suspended their campaigns.

Following the Iowa caucus, the New Hampshire primary is scheduled to take place Tuesday, Feb. 9, leaving the rest of the states to reach their decisions before the nominees are finalized.
