I think the notion that the Hastert rule is dead is a little premature. After all, subject to a discharge petition, and I cannot remember a single successful one, the only way something is scheduled for a vote is if the Speaker wants it to be scheduled for a vote. With the Fiscal Cliff bill and the Sandy relief bill, Boehner decided that he wanted a vote. The fact that many GOP members took advantage of strong Democratic support to vote against the bills, but still have it pass, doesn't really tell us much. Boehner may well have been fulfilling the will of his caucus by putting the issue to bed, and allowing his members to vote against it.
I could easily see the same thing happening with the debt ceiling. Here is what I think happens. The Senate passes a debt ceiling bill and sends it to the House. Boehner schedules a vote. Every Democrat votes in favor of it, as well as about 20 Republicans (nearly all from the Northeast) and the bill passes by a whisker.
Nobody wants to fight a war on the other guys territory. That is essentially the problem the GOP has with the debt ceiling fight, and Boehner (and some of the less brain dead members of his caucus) know that.
