Again and again, I've seen Bush turn a blind eye as his henchmen have leveled zealous attacks against his political enemies - assaults which the president himself has sometimes directly encouraged.
Again, President Reagan was sort of an amiable presence out at the ranch by the last 6 months of his presidency. He had no effect on national policy at all.
But I think what happened was that Clinton knew how to fight back. And the way he fought back was on the issues - being tough in staying on the things that mattered to people in their lives.
I mean, for all of his faults and the troubles in his marriage, Bill Clinton is still married to a girl he met in the library 25 years ago at school. Can we say that about many of our other leaders today in America, including on the right wing?
If George W. Bush is given a second term, and retains a Republican Congress and a compliant federal judiciary, he and his allies are likely to embark on a campaign of political retribution the likes of which we haven't seen since Richard Nixon.
If it was about lying under oath - we actually know that Clinton certainly was deceptive, as most people would be about their sex lives - but, in fact, he did not lie.
