Former Gov. Martin O'Malley dropped out of the Democratic race on February 1, the Iowa caucuses, freeing up his supporters to caucus for Hillary Clinton and Sen. Bernie Sanders.
The former governor of Maryland, who ended his term in 2015, launched his campaign in Baltimore shortly after sometimes violent protests erupted over the death of Freddie Gray. The former mayor of Baltimore used the backdrop of a divided city based on race and class to contrast his campaign's theme of inclusion.
The Democratic candidate's motto was "new leadership," drawing out a contrast with Hillary Clinton and Sen. Bernie Sanders who are both a decade and a half older than O'Malley.
If elected, he vowed comprehensive immigration reform, to reign in Wall Street, tackle climate change, allow for union organization, and increasing the minimum wage.
O'Malley struggled to register among a mass of voters lining up behind Hillary Clinton and Sen. Bernie Sanders. He rarely topped 2 percent in national polls.
