@Lash,
I went from one to the other, I'm not brainless, I'm not female, I'm not driven by soundbytes.
I would see your point if I agreed with 100% of Clinton's polices....McCain would seem like a crazy choice.
But I didn't agree with Clinton 100%, more like 40%. I agree with about 40% of McCain. The rest of my positions are not fully supported by either candidate. I only agree with about 35% of Obama's positions, but even worse I don't think he'll be anywhere nearly as effective as Clinton would have.
I can easily go from one to the other because I'm forced to compromise either way. I think there a lot of people that are like me in this aspect, and can easily switch sides.
