I’m not going to sugar coat it, Scalia’s passing likely marks the end of the Second Amendment if the Mitch McConnell and Senate Republicans don’t grow a pair. Just because Obama appoints a replacements doesn’t mean the GOP Senate has to confirm him or her. Once a replacement is named, I would make crystal clear to your Senator that you fully expect them to vote against any nominee who does not profess unwavering support for Heller & McDonald and the Second Amendment.
Oppose, Block, Filibuster. Run out the clock. Obama has had two appointments, and that’s enough for any President.
