It has a little something to do with her constant triangulation, a trait of her husbands that also drove me nuts. I also don't want a President just to the left of Joe Lieberman. But that is not the main reason.
Mostly it is this, and I know it is seemingly petty but nevertheless in the long-run I think it is important.
We are supposed to be a democracy not an oligarchy (or at least we should pretend to be the former). I know that is naive, but nonetheless I think we should at least keep the appearance. I simply cannot abide the United States going Bush-Clinton-Bush-Clinton. It's disturbingly anti-democratic looking if nothing else. This from David Kurtz sums up my thoughts exactly (apparently it is Talking Points Memo day here):
I think you may have touched on this before, but I'd like to reiterate the single biggest mental block that currently makes me think I will not cast my vote for Clinton. It makes my stomach hurt to think that in twenty or thirty years I could look back at a list of presidents that includes "Bush, Clinton, Bush, Clinton." This country is far too great to have to rely on two families for so much presidential leadership. Think about it: a two-term Hillary would be TWENTY-EIGHT years of Bush and Clinton. It's petty, but like I said it's a mental block, and I'm just not sure how I can get over it.
On the Democratic side I would vote for anyone but Hillary Clinton for the nomination, unless Joe Lieberman or Zell Miller enters the race. It's nothing about her capabilities, rather it is a block I cannot get over. There are many other candidates available of both sexes available that I would gladly vote for over Ms. Clinton.
Besides people, do you really want to enable another Bush to run in 2012?
This HAS TO STOP!
