Paul Krugman provides some perspective on the plight of those who saw Obama as a stronger progressive than he has thus far proven to be. Money quote:
But back to Obama: the important thing to bear in mind is that this isn’t about him; and, equally important, it isn’t about you. If you’ve fallen out of love with a politician, well, so what? You should just keep working for the things you believe in.
It's a timely message for many of us.
