Is George Bush the worst president-ever?

The History News Network at George Mason University has just polled historians informally on the Bush record. The results are summarized in this report. Briefly, out of 415 who answered, 338 said they believed Bush was failing, while 77 said he was succeeding. Fifty said they thought he was the worst president ever. Worse than Buchanan. This is what those historians said about the Bush record:

1. He has taken the country into an unwinnable Iraq war and alienated friend and foe alike in the process;
2. He is bankrupting the country with a combination of aggressive military spending and reduced taxation of the rich;
3. He has deliberately and dangerously attacked separation of church and state;
4. He has repeatedly "misled," to use a kind word, the American people on affairs domestic and foreign;
5. He has proved to be incompetent in affairs domestic (New Orleans) and foreign ( Iraq and the battle against al-Qaida);
6. He has sacrificed American employment (including the toleration of pension and benefit elimination) to increase overall productivity;
7. He is ignorantly hostile to science and technological progress;
8. He has tolerated or ignored one of the republic's oldest problems, corporate cheating in supplying the military in wartime.

So, is he the worst president ever?
