CNN reports that 56% of Democrats believe that Sarah Palin's crosshairs map was at least partly responsible for the Tucson shooting. This sounds ridiculous to most reasonable people, but we should remember that 61% of Democrats either believe that George Bush knew in advance of the terrorist attack on the World Trade Towers or are not sure.
This indication of loose marbles rolling around in the collective Democratic psyche should be kept in mind the next time an MSNBC host or newspaper columnist makes sport of the fact that some on the right are skeptical of Mr. Obama's provenance.
At least there's some reason to wonder where the President was born. There's no reason to believe that Sarah Palin had anything to do with Mr. Loughner or that George Bush had anything to do with 9/11. Sadly, some people don't need reasons.
