As a political tactician, I don’t have Karl Rove’s stature, or any. (Or should I say “strategist”? I’ll have to ask Senator McCain.) But one thing seems to me fairly obvious: Job No. 1 for McCain-Palin should have been to define Obama and Biden as too liberal for America. And that shouldn’t have been too hard. This is just about the leftest ticket we’ve ever seen. But have they done it? I don’t think so.
