Obama will not be behind a direct 2A attack, at least not in this term. He might sign on to one but he is not going to waste his limited capital on pushing for it when his list of "Societal Change" issues will most likely consume it all.
As I said, look out for regulation through Environmental issues (lead ammo taxes/bans) which if you oppose it's because you "hate the Earth" and especially be wary of who he sends to the UN the next time they come around looking to ban private arms...
