Except for national defense and terrorism, most other issues work better for Democrats than Republicans: the economy, oil prices, housing slump, health care costs. The piece concludes with an apparent non sequitur:
Americans haven't elected a sitting legislator as president in 47 years. And four of the last five elected presidents have been governors. The fifth one was a sitting vice president.
This isn't a non sequitur because both of the two leading Democrats are "sitting legislators" while the leading Republicans are not, and one of them is a recent governor. Specifically, that trend is a bad omen for Senators Clinton, Obama, McCain, Dodd, and Biden; great news for Governors Romney, Richardson, and Huckabee; and somewhere in the neutral range for Mayor Giuliani, and former Senators Edwards and Thompson. Isn't politics a great spectator sport...?
