Lets face it, Clinton isn't the most golden name in the Democratic Party anymore. A number of Democrats saw the Clinton-centric attitude out of that camp during the primaries. She doesn't hold nearly the power that she thinks she does -- or that people give her credit for. We saw that by the mass defection of supers midway through the nomination process.
I think she would've made a great opponent to McCain, and I think she would've been an even better President. I'm not afraid to admit that could even be a better President than Obama. Hillary would've gotten a lot accomplished with a Democratic majority in Congress. It'll be a learning curve for Obama -- not saying he's not ready, he's just not AS ready as Hillary.
After John Edwards dropped out at the end of January I had a difficult time trying to decide who I'd ultimately like more as the Democratic nominee. I had a certain amount of difficulty supporting Obama over Hillary. Health care is of prime importance to me, and frankly her plan is better in my eyes. But, by mid-February it was apparent that she wasn't going to win the nomination without a major event taking place.
I was glad she stayed in until the end, and I don't think it fractured the party; that's obvious now. But, it certainly cemented the party as the Party of Obama. Yes, there are still Clinton-ites out there that have hurt feelings. But, where are they going to go? McCain? That's a joke! They're Democrats, and they're a fraction of the party whole. They'll either "come around" and vote for Obama, write in Hillary, or stay home. They're not voting McCain.
