Why should they be embarrassed? They got the law that they wanted passed. Not a single one will lose an election over this. Even if a challenger brings it up, they have a very grateful industry behind them (and now with even more money to throw at elections).

If there is any embarrassment to be felt, it would be on the part of their constituents, who voted for this legislature and came out behind because of it. But I strongly suspect that they will re-elect the incumbents.
