Obama will not crusade anti gun bills. He will though sign any that cross his path. His stance on the 2A was well known until the revisionism set in at the start of his POTUS. It was a slick job and even fooled many supposed 2A supporters.
The fight to prevent the POTUS from signing such an anti bill is lost.
The fight now is to strike fear into the legislature that pushing 2A items may cost them their seat. It will not work with Pelosi and such but stands a good chance with those Dems who won in what were normally more conservative areas.
Or you can just claim we are all pawns of the evil Illuminati or Capitalistic Zaibatsu and concentrate on stocking your bunker like some here seem to do.
