1. The national STD infection known as the Clinton family will disappear if she doesn't win this election, and they know it.
2. Nobody in the Beltway establishment wants a wild card like Trump in the White House.
3. Obama can pardon Clinton, but with every passing day it's becoming more clear that HE has legal exposure here as well.
IIRC Alberto Gonzalez is the punk that instructed the ATF to implement the “barrel ban” on imported parts kits. Correct me if I’m wrong.
