There's an old and morbid joke whose punch line is, "Aside from that, Mrs. Lincoln, how did you enjoy the play?" It came to mind after U.S. Rep. Tom Cotton of Dardanelle recklessly compared President Obama's record for holding off terrorists with that of Obama's predecessor, George W. Bush. Bush's record was practically impeccable, Cotton said, except for 9/11. Exceptions don't come any taller than 9/11. Three thousand Americans died in the greatest terrorist attack that ever occurred on American soil, and it happened on George Bush's watch. Still, right-wingers like Cotton try to turn Bush into a peacekeeper. One of the most chowder-headed of the Washington pundits wrote a couple of days ago that Bush's legacy was "He kept us safe," the pundit overlooking both 9/11 and the thousands who've died in the bloody warfare that Bush led, or lied, America into afterward. Such revisionists are shameless. Except for that one night, John Wilkes Booth didn't shoot any presidents, but his is not a legacy to boast of.
