Pat Buchanan: It isn't Watergate yet, but how long can this sustain?

There’s no question that the agenda has been put on the back-burner. At least for the cable networks and the newspapers with all these conflicts. There’s no question that the agenda has suffered. I think the president has been hurt to a degree if his approval rating is around 38 or 40 percent. The Republican Party is sort of mute right now on Capitol Hill. This has been a dramatic four months. The question is, is can we sustain this kind of intensity for 44 more months?
