""As noted here, when the president first used the device, the legal justification was penned by the legal advisers to Mr. Obama’s predecessor, George W. Bush. In a 2005 memorandum, the lawyers concluded an autopen signature would carry the weight of the law.""<quoted text>
It was the timing, Lily.
Any president who would put his vacation first over signing a major piece of legislation would be considered narcissistic and arrogant.
If Bush had been victorious in passing a major piece of legislation that liberals considered crappy to begin with and then took off to his ranch before signing the darn thing, you wouldn't have had anything to say about that?
Again, be honest.
You lose again, smokey!!
