Well, its not, in my opinion, that Hillary is smart. I agree with you there. But I believe her advisors will be top notch & the Media protection more complete than it was for Kerry (see my other post below.)
So I anticpate a very bad fight to stop Hillary, I hate to say.
I think hindsight says that she would have had a better chance right after Slick Willy or the first run against Pres. GWB. September 11th, the GWOT and 43 were all factors they did not foresee and cannot control.
