Well,
it'll be interesting to see how this plays out for Obama. I can only hope (as an Edwards supporter #1) that it helps him.
And I also hope his progressive rhetoric/positions continue to influence both Obama and Hillary, especially knowing that they'll likely become more conservative when we get to the general election. The last thing we need is a watered down centrist to help move the country from far-to-the-right to "right of center".
Unless people think the war, Patriot Act/spying and massive tax cuts (and on and on) were somehow "moderate" things to begin with.
