Maybe President Obama just likes being the underdog (as much as someone can be the underdog while President of the United States). His White House and Congressional Democrats are finally taking the offensive when it comes to the debate over the health care reform bill. The Dems are aggressively talking up the fact that the Republicans want to increase the number of uninsured people, allow insurance companies to set premiums in monopolized markets, and re-establish the Medicare donut hole. That is, Republicans are wasting time by trying to repeal the entire health care reform legislation, even though there's no chance that repeal will pass the Senate or get President Obama's signature, and the Dems are amping up their efforts to show the absurdity and danger of this effort.
My favorite move is that the Obama White House has purchased the Google search term "Obamacare," conservatives' appellation of choice for health care reform, so if you search for that word the first hit takes you to the Administration's website that explains the reality behind the health care law.
Finally the Dems are coming out swinging. It only took two years.
