We have three plausible candidates remaining–Obama, Clinton and John McCain–and Obama has proved himself the best executive by far. Both the Clinton and the McCain campaigns have gone broke at crucial moments. So much for fiscal responsibility. McCain has been effective only when he runs as a guerrilla; in both 2000 and ’08, he was hapless at building a coherent campaign apparatus. Clinton’s sins are different: arrogance and the inability to see past loyalty to hire the best people for the job and to fire those who prove inadequate. “If nothing else, we’ve learned that Obama probably has the ability to put together a smooth-running Administration,” said a Clinton super-delegate. “That’s pretty important.”
