Okay, others may have predicted this, but I didn't hear them. One can only imagine what the executive action will be. But clearly even this White House realizes there are limits, with Vice President Joe Biden saying "separate legislative action would be required." So they're going to use Executive Orders to make some changes in gun law; most likely the Assault weapons and high capacity magazine bans. That's what the anti-gun crowd claims it wants right now. And they may try even more than that.
If I'm right on that then the legislative proposal would likely be sweeping.
