HE did NOT sign it - a machine did ...
That is the crux of the issue ...
AND, he DID NOT have to leave town before signing - he coulda put the paper up to the door of Marine One and signed there just before leaving ...
Yes, a machine is not the President. He didn’t sign it, so it’s not law, as far as I’m concerned.
This just isn't unconstitutional. The Constititution says he has to sign the bill. It doesn't say how he has to sign it, or what implements he can or can't use. It just says he has to sign it. His signature is affixed. By his autopen. With his permission and intent. He signed the bill.
There isn't a Court in this country that is going to rule that a bill is unconstitutional because the President used a automated pen to sign a bill rather than a ball-point pen. It is a petty technicality at best. If a staffer forged his signature, with an autopen or a regular pen ... then you have an unconstitutional bill.
Does it matter whether he had to leave town? That's certainly not anywhere in the Constitution.
