And then there were two.
The Democratic nomination became much more clear on Monday night after former Maryland governor Martin O'Malley suspended his campaign.
“In a tough, unprecedented year, O’Malley spent more time in Iowa than any other candidate and remained the most accessible,” an associate told the Washington Post.
“He ran an energetic and honorable campaign — leading the field with the most bold progressive policy proposals, and he successfully pushed the other candidates on gun safety, immigration, and climate policy.”
His campaign's decision comes as no surprise after O'Malley's poor showing in the polls — he never hit numbers higher than single digits nationally.
After the 53-year-old longshot's exit, former secretary of state Hillary Clinton and Vermont Senator Bernie Sanders remain the final two candidates in the Democratic contest.
