A useful counterpoint is Harold Meyerson's op/ed directly below Mushroom Cloud's, "The Can't-Do Blue Dogs," which, as you can glean from his title, looks at the same "moderate and conservative Democrats" as Mushroom Cloud, takes the Rethug opposition as a given, but asks the pertinent question:
"Why Democrats of any ideology want to cripple their own president in his first year in office, and for seeking an objective that has been a stated goal of their party since the Truman administration, is a more mysterious matter."
Indeed. Unless they're DINO's more interested in holding onto their seats than in supporting their party's leader and agenda, and taking a chance to recast America's health care to benefit millions for decades to come. Wanted: A few profiles in courage.
