These seem like the kinds of differences that can be ironed out during, say, a floor debate of [the] Dodd bill. The trouble is that Republicans have banded together to filibuster a measure to begin debate. Not to pass the bill, mind you. Exactly zero members of the Republican Senate caucus could be found to vote in support of the measure to begin debate. Despite the apparent similarity of philosophies in the parties' approaches to regulatory reform. How is one supposed to move from that to a good faith effort to negotiate away differences?
