Ehhh...nah. He will bluster for a couple more years. Then he will be a lame duck. Then he will be gone like every other president and the republic will roll on as it does. Those who see Obummer as some existential threat give him way too much credit. At worst he might extend background checks and ban some high capacity magazines. That and HCR will be the cross we have to beat as Americans moving forward, hopefully to be undone by some future Republicans. This country can and has endured worse.
