He definitely didn't say specifically whether he voted Trump or not. Either way it seems like he's admitting it was a mistake if he did, or at least that was my read of what he said.
Cross posting here (this was also in V&N):
Russillo: You already have your base - the people that voted for you are voting for you again, so I don't know that you have to be this antagonistic throughout the whole thing. Now, look, I'm not exactly a guy that had a "Hope" bumper sticker on his car during the Obama stuff, but I know this -- and look, you know, the way I would vote is I would vote selfishly. I think most of us vote selfishly. Like I voted for tax purposes, you know. I voted for tax purposes when I had no money and I had...voting...and I know some people who can say well that's pretty self--I actually think most people vote selfishly anyway.
I also think that people that I know that voted for Trump -- I don't know that they did it because they're this, you know, the person that's getting off on all these horrible tweets, I think they looked at Hillary and they were like "I'm sick of the Clintons, I think they're crooks too, and that's why I went and voted this way," you know, and that I kind of get. And if you voted for Trump you don't want to be wrong. Like if you're super passionate about it and you're very conservative, and this isn't a criticism of it, but let's face it, you just don't want to be wrong. You don't want to be -- you don't want to believe that you could be so wrong about a President.
