Why would the Democrats back a Presidential candidate as psychologically damaged as Hillary Clinton? Why would they back someone power-obsessed to the point that she has broken numerous laws, given new meaning to the words "dirty politics" and stood by her husband as he humiliated her because she just had to be a politician? Part of it is that most of them can relate to that kind of lack of morals. But there's a bigger reason:
They think that she can win.
Think about exactly when the Democrats went completely off the rails. It was the second that President Bush won the Presidential election in November of 2000. Even while the recount was going on, most of them knew that Bush had won, whether they wanted to admit it or not.
It was bad enough for them when Republicans took control of Congress in 1994, but when we took the White House too, it propelled them back in time to their miserable childhoods, when they always lost at everything - physically, socially, academically - you name it. Living life as perpetual losers and misfits is, in fact, what made them into the Leftists that they are today. Just look at any anti-Bush - err, anti-war - protest and you'll recognize the same losers that you went to school with.
They can't bear to lose again. If they're not actually psychotic at this point, they would certainly be so after another loss. It would bring back just too many bad memories and, of course, make them feel bad.
And they figure that they've had enough of that for one lifetime.
And so, they're willing to ignore what an absolute scumbag they would be putting back into the White House. Not to mention Hillary's felonious husband. They don''t care. To them, the end always justifies the means.
Especially when it keeps them from reliving the Hell of their depressing childhoods.
