Actually, he has written in the past that he is not voting for either Clinton or Trump, as neither represent his political views.
The public endorsement of Clinton is a self defense move.
No, I think he is simply pointing out how unhinged some Clinton supporters are acting (at least the ones that have posted to his blog).
So they apparently switched to trolling the comments section on the blog, creating sock puppet accounts to post racist and sexist responses that pretend to support Trump. So, he has disabled comments altogether.
Exactly.
Adams is no dummie -- he knows who and what comprise the unhinged loony fascist Left:
"So I’ve decided to endorse Hillary Clinton for President, FOR MY PERSONAL SAFETY.
Trump supporters don’t have any bad feelings about patriotic Americans such as myself, so I’ll be safe from that crowd. But Clinton supporters have convinced me – and here I am being 100% serious – that my safety is at risk if I am seen as supportive of Trump. So I’m taking the safe way out and endorsing Hillary Clinton for president."
