Another Republican doctor is speaking and reminding Obama how unpopular his plan is. Then he goes after Obama’s assumption that people with catastrophic plans get worse care or don’t get preventive care. Not true, says the doctor. In this case, the speakers, their background, and their demeanor have more to do with the argument (again, if anyone is still tuned in) than the substance. For once, Republicans have some appealing and informed speakers. Obama, never one to respect his opponents, plainly didn’t bank on this.
