Do the math
Let’s see . . . 5% of the population thinks Elvis is still alive somewhere; 2% believe they have been impregnated by space aliens; 3% think the world is flat; 3% think smoking is good for you; 4% think the moon landing was a hoax; etc., etc. – – anyway, when you add all those people up you get the 25% of the population that thinks Bush was a good president.
