The much smaller and non-lethal Bush program was terminated as a failure. It was intended to actually TRACK the weapons, but didn't work as intended and was discontinued. Why would obama take a program that was cancelled because it clearly did not help solve drug crimes along the border, and increase it ten-fold, with no tracking devices at all, and without even telling the Mexican government what was going on?
This is a red herring to detract from the gravity of this insane operation. The excuse that "Bush did it too" is no excuse at all. If Bush was a child rapist, would Obama child rape then be OK? And in this case Bush DIDN'T "do it too"
