Well, if Bush were to do what Lincoln did, he would most likely be impeached. Lincoln had a Member of Congress arrested as a Confederate sympathizer becauise the guy disagreed openly wiht his war policy.
Clement Vallandingham of Ohio, the "man without a country".
A small, but important correction. The man was a former member of Congress (voted out by his constituents as I hope John Murtha will be in November) who published a newspaper that encouraged Union soldiers to desert from the Army.
Lincoln said something along the lines of "Should I arrest one old fool or allow him to continue and be forced to shoot some young men foolish enough to listen to him".
Lincoln arrested the old bastard and had him shipped South (they didn't want him either).
It would be fun to watch Lincoln deal with John Murtha today.
