How about Martin O'Malley for POTUS 2020?

[elleng]

95. But you know this, and many other things, kwassa:

'served as the 61st Governor of Maryland from 2007 to 2015. He previously served as the Mayor of Baltimore from 1999 to 2007, and was a councilman from the Third Councilmanic District in the northeast section of the city on the Baltimore City Council from 1991 to 1999.

O'Malley served as the chair of the Democratic Governors Association from 2011 to 2013, while being governor of Maryland. Following his departure from public office in early 2015, he was appointed to The Johns Hopkins University's Carey Business School as a visiting professor focusing on government, business and urban issues.

As governor, in 2011, he signed a law that would make illegal immigrants brought to the United States as children eligible for in-state college tuition. In 2012, he signed a law to legalize same-sex marriage in Maryland. Each law was put to a voter referendum in the 2012 general election, and was upheld by the majority of the state electorate.' https://en.wikipedia.org/wiki/Martin_O%27Malley

and: in New Hampshire:

Did I just witness the start of the 2020 presidential campaign in NH?

SALEM –Martin O’Malley preached reforming the Democratic Party and taking “our country back” at the first stop of his first visit to New Hampshire since the 2016 election.

And while he says his trip to the first-in-the-nation presidential primary state was all about 2018 rather than 2020, O’Malley’s address to a group of Democrats at a house party in Salem may be the beginnings of a stump speech in the next race for the White House.

'Tonight, Democrats won a huge victory in New Hampshire! The people of the Granite State elected a Democrat to the State Senate - claiming a seat Republicans held from 2010-2016. We have the momentum behind us to continue winning across the country in races up-and-down the ballot.

Can I count on you to support Democrats across the country?

I was honored to join Senator-Elect Kevin Cavanaugh in New Hampshire last week to help get out the vote. Because of this win, Democrats are now only 3 seats away from flipping the chamber.'
