The Republicans, through their leadership both in Congress and on the airwaves, have come out overwhelmingly against "Obamacare." They don't deny that health care reform is necessary, they simply oppose anything the Obama camp proposes (even stuff thrown in there by Republicans).
I think it's a fair question to ask "What is their alternative? What do they propose instead? If you don't have an alternative solution, then why not work with the administration to figure out a reasonable compromise?"
As far as I can figure, the opposition's position is "we don't like anything proposed by the Democrats, but rather than try to come up with our own ideas, we're going to to oppose this until it's in the dirt and then use the fact that there's been no health care reform as a launchpad for the midterm elections." Am I wrong? Other than saying "this isn't right," what else has the Right offered?
