Bush is not running again. What people want a great sense of "throwing off" not only the Bush years, but the '90s too.
Let's face it, although the Republicans were obsessed with the Clintons, the Clintons were also cheap, dramatic, self-absorbed. Their White House was an exhausting soap opera. Bill thought the presidency was about him, rather than, well, the presidency.
The way Hillary has run her campaign reminds us of what we're in for if she wins. Prior to the Iowa caucus she had to fire two people for making slurs about Obama, suggesting he was a closet Muslim, etc. Now, either that was terribly cynical and she wanted those slurs to come out, or she doesn't have much control over her campaign. And all the news from her campaign has been about in-fighting, chaos and all that.
Whereas Obama has run a pretty solid, even placid campaign in contrast.
We can be sure we're going to go back to another "Clinton years" with scandals and scandalettes of all sorts, Billy's indescretions, etc. No thanks. Even Clinton lovers are tired of that stuff.
Hillary has a lot of juice. She's going on past Feb 5th even if she's blown out. She still has the Democrat machine behind her. I would not count her out one bit.
What she has to do however is realize where the country is emotionally. Truly, issues, especially as they pertain to the Democrats since they are all basically in rough agreement with each other, are taking a back seat to this real hunger for a break with the political past. And unfortunately for Hillary, that includes her.
She needs to connect emotionally with people as well as with their heads. It's clear that even since Iowa she's still not figured this out.
