I realize that the editorial made that supposition. However, it doesn't really follow that the Obama-Mac incident is particularly telling one way or another.

Mac is a comedian best known for his role in a now-cancelled family-friendly sitcom and PG movies.

Wright was Obama's pastor for twenty years. Ahmadinejad is in the news on a daily basis and, further, the object of much discussion and analysis among members of congress.

As I mentioned before, there's plenty of matter of substance over which to attack Obama. In that context, going after him on the question of whether or not he was sufficiently familiar with the comedy stylings of a supporter is not only a bit petty, it's counterproductive.
