Nobody will think less of you if you grunt and punt on this week’s Republican National Convention. Go ahead and scan the newspaper and Web accounts of the event if you must, but feel free to watch something else on TV. The same advice goes for the companion production by the Democratic Party in Charlotte next week. But whatever you do, don’t bemoan the attendance of 15,000 reporters trampling one another in their frenzied attempts to get a slice of the thin story, or complain about the wasted money sending them there.
