If you haven't yet, set aside about 20 minutes and watch his fantastic acceptance speech.
Like he said, it will be an uphill battle. It's a lot harder to build things up than tear them down and our economy, civil rights, and world standing need more than a little clean-up.
In other positive developments:
California (my home and current state) passed propositions to build high-speed rail lines between northern and southern parts of the state (the number everyone quotes is 2 hours and 40 minutes between San Francisco and LA, though the due date is the year 2030) and another to raise minimum standards for the treatment of farm animals.
The state of Washington approved a proposition allowing doctor-assisted suicide for terminal patients with approval from 3 doctors, allowing them the dignity to escape a painful end of their life; Michigan approved a proposition to allow stem-cell research.
And California, Colorado, and South Dakota upheld women's rights to abortion.
Ironically and sadly, at the same time we made history by electing our first African-American president, Arizona, California, and Florida banned gay marriage (and Arkansas banned adoption of children by non-married couples, designed by the promoters to prevent adoption by gay couples).
I still don't see what's so hard to understand about equal rights. There's no difference between banning inter-racial marriage and gay marriage; in both cases, a privileged majority spent time and effort to make life less enjoyable for a minority causing absolutely no threat to their own happiness (they'll also both be legal, in time). It's the ultimate in selfishness and moral depravity championed mostly by the religious right (who have the gall to claim they're the models of ethical achievement).
On the other hand, with the exception of Florida's, these propositions just barely passed. So if equality hasn't won yet, it's getting much closer. And with any luck, the new Executive and Legislative branches of our government can help grease the rails for future progress.
