Loser may be harsh, but I think it's fair to say someone leaned on him to float this trial balloon. Three guesses as to who?
It does seem kind of odd that Pence waited right up to the time the Senate was voting on their amnesty to release his "plan". It's almost as if he intentionally threw this monkey wrench out there for the sole purpose of gumming up the works in the enforcment first strategy of the House. This is very disappointing.
