At the risk of being written off as a cynic, let me dust off the old adage: "When in doubt about what is expedient, do the right thing." Though there probably are no upsides here for the Congressional GOP, we can wave our arms and talk ourselves blue discussing what is the course with the least downside for the country and for the Republicans. In reality, there are too many imponderables here, so we simply do not know. We do know that a tax increase would be bad for the country, would not do anything useful about the deficit, would encourage more spending, and would pave the way for further confiscatory taxation, eventually at the expense of the Middle Class. That is all the GOP needs to know to oppose it, come what may.
