I'm not sure about this guy...  My main issues with him -

1.)  Running for Senate without any legislative / governmental / legal experience.  Run through a couple House terms and show us what you've got first.

2.)  Enlisting and requesting Infantry and Iraq.  After having protesting that specific war.  He says he wanted an adventure - maybe he just wanted to kill people?

3.)  After his tours, he worked for Blackwater (Constellis).  His response was they had a different name by that time, and it wasn't the same company.   It was the same company.   The name change was a PR move after bad press - Eric Prince just moved from CEO to COTB so he had plausible deniability on management decisions.

4.)  The Tatoo didn't bother me as much as the video where it is shown. Where he is shitfaced, in his underwear, at his sisters wedding!   That was a real good look, buddy.

5.)  The reddit posts are not good, but there is the mitigation of time and a shitposting youth that dull that issue.

He is hewing to the progressive line, but there are too many contradictions in his past to make me fully believe it.  His excuses have always centered around ignorance of his actions, and he reeks of an opportunist.  If I lived in Maine, this progressive would hold my nose and vote for the establishment Dem.
