Jonathan Bernstein compartmentalizes the Republican legislative agenda. It's mostly political posturing, as this anti-earmark John Boehner op-ed should make clear. Bernstein's guess on healthcare:
I see two paths on health care that would at least plausibly work for the Republicans. One is to do a repeal-and-replace vote in the House that involves passing an entirely nonworkable bill designed to include all the goodies in ACA, at least on the surface. It doesn't matter if there are no works inside; after all, the bill wouldn't stand a chance in the Senate, so it only needs to be designed to deal with attack ads, not the real world. The other, and better, path, is to just do a bill to eliminate the individual mandate. Of course, policy analysts will point out that without the individual mandate the ACA won't work -- but good government truth squadders would probably not give their seal of approval to attack ads saying that it's a vote against coverage for preexisting conditions.
