Very true, IF we could pull that off, actual Republic(ans) in the Senate, this would be the best course of action - let them have the pres and take two houses in trade.Not only the presidential election but also the Senate will need to be pro 2A. They approve presidential nominees for the Supreme Court. If the Senate goes anti 2A in the 2016 election it may not matter much
The trouble is that few if any of the sammich makers we've sent to DC with "R" on their paws have had the stones to really block such a nominee. Worse yet, some of Bush I and II's appointments are still haunting us.
If you are going to take this path, then Browns, McCains, et al. need to go as well.
