B HO who came in as the most anti-gun president talked of the reinstating the (failed) Clinton AWG all the way up to the day he was inaugurated and that day, they pulled it off his website. He didn’t do much. Not sure if their base will allow a rerun of B HO.
I seem to remember that handgun carry in the National Parks, thanks to Tom Coburn, occurred when Obama had both the House and the Senate in his corner.
