http://my.barackobama.com/page/community/post/samgrahamfelsen/gGBslbAs a Democratic National Committeewoman, I have felt it my duty to let this unique presidential campaign process play out, one that has reached across the country and engaged millions of Americans in expressing their preference for a Democratic nominee before expressing my preference as a superdelegate. I am now convinced that it is time to pull together behind a single candidate who has the backing of a growing number of Americans. I therefore announce my wholehearted endorsement of Senator Barack Obama.
