National Review's Ramesh Ponnuru calls IWV's ObamaCare Repeal Pledge the “most ironclad pledge I’ve seen out there:”
If the Democratic candidate takes the pledge, then the Republican has (a) done some good and (b) made himself look like a leader and the Democrat like a follower. If the Democrat refuses to take the pledge, he has exposed his stated opposition to Obamacare as a pretense. Either way, it’s a win for conservatives.
