How about Martin O'Malley for POTUS 2020?

[Hortensis]

48. Yes, I vote for or against the candidates. Period.

I certainly wouldn't refuse to hire a good roofer because I didn't like a neighbor whose house he worked on.

They only matter if they reflect something important about the candidate himself or herself. I didn't pay attention to Pat Buchanan when he ran, so knew little about him, but all the racists and other bad characters who came out of the woodwork to support him were an eye-opener. They said things about him that he was careful not to reveal on the national stage.

I like everything I learned about O'Malley during the campaign, but before voting I would have to find out why in early 2015 Maryland Democrats polled only supported MoM 3% and Hillary 63%. Reasons might aldo say good things to about him to me, but always more to know.
