The best piece I've read on the convention is right here.

All of which suggests that Republicans are rarely offered advice because there is not much to advise them on. Republicans do not need to be told whether to take the high road or the low because they always take the low road. They do not ponder whether brutal campaign tactics will affect their ability to govern, since they care so little about government. If liberal media pundits are not particularly interested in offering conservative politician advice, conservatives understand their role as cheering their side on. No wonder Democrats are viewed as more likely to make mistakes. You can only make a mistake when you have a choice.

Excellent points.
