The schism on the right about how to approach Obamacare continues. Douglas Holtz-Eakin, a longtime critic of Obamacare and former CBO director for a previous GOP Congress, weighs in today with his suggestion in "Yes to Exchanges." He pulls out some of the right's greatest rhetorical hits from the past three years to warn that the tack some Republicans have taken on the state level is unintentionally embracing a "single-payer Trojan horse." The alternative, if states decline to design and operate their own exchanges, is a federally-facilitated exchange--an option several conservative governors have already chosen. Holtz-Eakin doesn't like this one bit: This is spicy stuff! I have to say, watching the debate on the right about what to do now is fascinating.
