The 2A is not in Obama's sights right now
Sure it is. Obama wants a new "assault weapons" ban. He's already said so. New legislation has been drafted by Democrats in congress, and it is ready for passage. And ready for Obama's signature. None of you seriously doubt that Obama will veto that legislation, do you?
And that'll be just the beginning: wait for new restrictions on ammunition ('armor piercing'), taxes (noting like raising taxes on guns and ammunition), and 'sniper guns', which will probably be included in the assault weapons ban. After all, you really don't need powerful ammunition, powerful scopes, muzzle breaks, and more than a two shot capacity to hunt, you know.....
