You think Hillary, having lost the primary should run as an independent. If Obama had lost the primary, how would you have felt if he had lost an independent run while Hillary was trying to take back the White House?
Practically speaking, Hillary would not have a chance of being successfull running as an independent as her appeal would come almost entirely from parts of the democratic base, without winning over any republicans, and with few independents. It wouldn't be a big enough tent to win an election, but it would definitely be sufficient to fragment the democratic vote in key states and guarantee a republican victory.
I think it is the last 8 years that people would argue needs to be vetted. The library, the speeches, the foundation. And the guy's unpredictable behavior. Something is very different about the way he's been acting. Would he continue to act this way as second spouse?
It wasn't about the Clinton's being racist. It was about them indelicately discussing (and playing to) racial divisions when they should have known much better.
Take, for example the infamous "hard-working white" people comment Hillary made. Can you imagine if Obama had taken a similar tack and said that Hillary had a problem with winning the vote of "hard-working males"? It would have been rightly panned as an appeal to sexism. And Hillary's comment was rightly panned as an appeal to racist sentiments.
Why settle it in Denver? If Hillary can't get together the votes there, why not wait until the day before the election to decide who will be the nominee? Hell, we've already given the gift of the last three months to McCain when the outcome was clear, why not give him the next five?
