The guy has been in congress less than one term. Where is the evidence that he is actually a “progressive” wearing conservative clothing now versus your typical garden variety common political whore who will simply change spots to further their career?
He's a Democrat. That's all the evidence we need.
Remember how many "moderate" or even "conservative" Democrats there supposedly were in the Senate prior to the first votes on 0bamacare? Heck, it almost felt like most of the Democrat caucus in the Senate was "moderate" or "conservative" the way they were talking.
Any notion that "moderate" or "conservative" Democrats are nothing more than mythical creatures should have died the day when all 60 of them voted to advance 0bamacare. As for the House, we're starting to see the same thing happen with more Democrats caving towards voting for this.
The only people being fooled are the ones who continue to believe that there are "moderate" or "conservative" Democrats who will swoop in and save the day.
