As Sam Rosenfeld explains, there's a different between the corporate whore caucus and legitimate ideological disagreements by centrist Democrats. I can see the "moderate" or "centrist" label being applied to a bunch of positions on economic policy questions, such as opposing increases in the minimum wage or supporting passing general business friendly laws (As opposed to industry or company specific giveaways). I may or may not agree with any of these things, but I'd be willing to say that those Democrats who vote for them could be legitimately called "centrists." But, for something like the Bankruptcy Bill, we're just talking about a split between Whores and NotWhores.
