Frankly, at this point I hope they uphold it.
Consider: it's struck down and the libs go crazy. It gives 'bam the one single thing he lacks this go round: an issue.
If they uphold the law, it will energize the Republicans and sway the fence sitters our way.
I can't help but wonder if this wasn't a set up all along; pass a bill knowing it would be struck down in order to exploit it in the next election.
I wish this wasn't possible, but I'm seeing you can never underestimate the stupidity of the electorate.
