He is. He endorsed Gary Johnson. Far out, man.
He went a little off the rails when the Billy Bush tape came out. But it looks like Scott is back on track now. He has taken a lot of heat, death threats and considerable loss of income over his observations and support for Trump. I wouldn't place a lot of credence in his “endorsement” of Gary Johnson. At one point he also said he was “endorsing” Hillary for his and his family's safety. The Johnson “endorsement” is the same.
Scott Adams endorsed Clinton, then Johnson, because he literally got death threats etc when he endorsed Trump. It’s well understood that his “endorsement” is B.S.
