The Republicans wisely chose Sen. Lamar Alexander to respond. He is polite and restrained but forceful, telling Obama that voters in New Jersey, Virginia, and Massachusetts rejected the approach to health care that Democrats passed last year. He explains that we need to “start from a clean sheet.” He reminds everyone that Obama is seeking to slash Medicare and raise half a trillion in new taxes. He notes that when those taxes are passed through insurance companies, premiums will go up. He is methodically explaining the most objectionable features of Obama’s plan, including the “sweetheart” deals. All in all, a good moment for the GOP.
