Most likely; I've never met him and haven't even read much about him as a private person, though, so I venture that opinion based only upon 'general impression.'
I don't think politicians are particularly evil as a class, by the way. There is of course the specific effect of an attraction to power--that's part of politics, and a part that can bias the sample, since power-lust can manifest in really bad ways. But it doesn't always show up that way; think of the athlete who always wants to have the ball in his hands, no matter how dire the situation: he knows that he's good, and that no-one is going to try any harder than he will. That's the positive face of the desire for power--in some, it looks like a desire for responsibility. I think that's not uncommon among politicians, many of whom are, I think, quite sincere when they say that they are in it to "do good."
It's also true that politics entails endless compromise and much horse-trading--and that's the good part, given that the alternative is unbridled power which can ride roughshod over everyone else! But the backroom deal, the crass trade-off and such are never inspiring, nor particularly edifying. It often seems that in the real world the right thing may have gotten done, but generally not for what anyone would call the right reasons. And all of that creates a certain 'grubbiness' that adheres to the political profession.
In the US right now, it seems to me that it's worse than that, though. In addition, there's now a level of partisanship and ideological blindness that has resulted in the dysfunctional Congress we all--well, about 90% of us, by actual polling data--witness with disgust. In my opinion, it results from a dysfunctional media in which spin often becomes outright lying, and which has become largely unrestrained by legal or social sanctions. That has meant the death (or at least serious illness) of the old saying that "You are entitled to your own opinion but not your own facts"--everyone now operates from their own little set of "facts", too many of which may not be true.
And that's an evil that is systemic, not personal.
