I agree with Victor that we should not exaggerate our differences. But I have met with many, many people in both the Romney and McCain camps, and read the commentary of their supporters, and in my experience it is not true that Romneyites are more anti-McCain than McCainites are anti-Romney. (I have watched both men enough to conclude that McCain dislikes Romney personally far more than Romney dislikes McCain.) Anyway, there are enough questions about what kind of president McCain would be that I think it would be a mistake to discourage the gathering of evidence.
