Yeah, she's gotta wait for '08. The big thing this year would be to make sure that Kerry loses, and that she's indicated for succession. That would mean primarily making stopping a new "star" like Edwards from being future competition. Gotta be a throwaway dullard who doesn't cost them a Senate seat - maybe Clark?
Certainly if she got the VP nod herself she could eclipse most other future-runs, but the danger is that Kerry/Hillary will be beaten too badly, and be a Dull/Duller campaign. Hillary ain't exactly exciting. And some blame may fall to her. Particularly when the Rats get serious about getting elected again and grow introspective about how they might have been a little lackluster in the WOT, and wrong on taxes, the UN, ...
Remember how running with Gore sucked all visible life out of Liebermann? Imagine Hillary sucking it in and having to support the top of the ticket when it ain't her?
She also has the small worry that Giuliani might take her on for her senate seat in 2006. I doubt he will, but a defeat would be a big downer on her resume'.
I hope she does try to run in '08... do you realize the research that we are going to be able to do over the next 4 years??? she'll be lucky to make it to the end of her senate term...
