Well, Krugman nails it again.

First, he cites a study that predicts that, a plan without mandates would cost $4,400 per newly insured person, and one with mandates would cost only $2,700, because the young and healthy will take their chances, leaving only those already needing medical treatment on the plan.

His summation nails it:

But while it’s easy to see how the Clinton plan could end up being eviscerated, it’s hard to see how the hole in the Obama plan can be repaired. Why? Because Mr. Obama’s campaigning on the health care issue has sabotaged his own prospects.

You see, the Obama campaign has demonized the idea of mandates — most recently in a scare-tactics mailer sent to voters that bears a striking resemblance to the “Harry and Louise” ads run by the insurance lobby in 1993, ads that helped undermine our last chance at getting universal health care.

If Mr. Obama gets to the White House and tries to achieve universal coverage, he’ll find that it can’t be done without mandates — but if he tries to institute mandates, the enemies of reform will use his own words against him.

If you combine the economic analysis with these political realities, here’s what I think it says: If Mrs. Clinton gets the Democratic nomination, there is some chance — nobody knows how big — that we’ll get universal health care in the next administration. If Mr. Obama gets the nomination, it just won’t happen.

Got your back, Doc.
