“Is the bridge gappable (as Mr. Cantor might say)? Yes, if the Republicans are interested, but only because neither side has really grappled with the cost issue. When Aunt Minnie back in the district has a hip replacement (her second) and gets a bill for $90,000, the challenge is not to find someone other than Aunt Minnie to pay. The challenge is to deliver hip replacements for less than $90,000, or tell Aunt Minnie she can’t have one.”
