At the end of the day you can pretty much do whatever you want. Eh, I'd say the history of "gun politics" in the last two decades suggests that's not true, or a bunch of politicians who passed or supported (Al Gore) gun control and ended up spending more time with their families just aren't good at playing this game. Assuming you believe they wanted the office more than the gun control bills, which in the case of the sunsetting and now sunset Federal "assault weapons" bill would seem to be particularly pointless.
