Add to the fact that McCain will most likely cut into Hillary's support in the north and pick off some northern blue states and have more appeal to independents, my guess is, he most likely will be very competitive in California, on top of all that McCain is a "media darling" the media loves him, he comes off warm and friendly, and if those two square off in a debate McCain wins on charm alone. Lets face facts here, Hillary is basically a media invention. To be honest, my personal opinion is that there is a better Democratic woman they could nominate,
Sen. Dianne Feinstein, I think she is better qualified to be president, she comes off on camera better than Hillary does, she is nowhere near as polarizing as Hillary is, she's California's most popular politician, she serves on the powerful Armed Forces Committee and Intelligence Committee, and it will be difficult for the pubs to tag her with the cut and run moniker, plus I see her being more appealing to the south and independents than Hillary.

In any event I seriously doubt Hillary will run, the risk is too great for her to lose, and her political career will be greatly diminished if she loses, I suspect that if the democrats take the majority in the senate it will weigh heavily on her mind that she can have a very distinguished career in the senate and easily win senate majority leader if she chooses to run for that post and have great influence, especially if we have a democratic president in 2008...Its something for her to give serious thought to.
