Technically speaking, wouldn't Bush being the greatest President effectively make him number 1?
That is technically speaking, of course; not reality. In reality, Bush is in strong competition for being worst ever. He still has Hoover, Carter, and Nixon to get past, though.
But I suspect that while Hoover brought us the Great Depression, Carter brought us immense taxation, and Nixon brought us Watergate; that Bush will win the whole thing when, not only did he bring similar pain to those others, but also much higher death tolls.
I mean you've got thousands of American soldiers, thousands of soldiers of our allies, and millions of Iraqis and Afghans. Carter, Hoover, and Nixon never pulled that off.
You might make the case that FDR pulled off similar kill totals. I could see that argument. But for it we got a win in World War II. Bush got us...turns out nothing. China is getting the oil deals, and Iran just picked up a new ally.
Not exactly the best investment of our money, equipment, or lives that this country ever did, you know?
