All of that may be true - but seriously, given the people that are in power now - does it really matter?
Obama could pass some crazy ass anti-gun EO and what would happen? Either Congress or the Supreme Court would have to slap him down somehow.
When I see stuff like this pop up I think to myself: I wonder what other screw job they are going to use this little threat as a bargaining chip to get passed?
What happens here is Obama threatens to EO a complete ban on assault weapons or high cap mags or some such thing, then when the Republicans in Congress feign outrage - he says: sure, Ok - we can let this one go as long as pass a hugely higher debt ceiling.
Screwed one way or another - personally if I was forced into choice I would have them pass the debt ceiling so I would still have my guns around when the whole train finally goes completely off the rails.
