Treason. There's no other word for it. What would people have said in WWII if a congressman had proposed cutting off funding for the war? It's treason, pure and simple.
Unfortuantely, this is not unprecedented.
Of course. However, there isn't anyone anywhere in the Halls of Power that actually wants to do anything about the treason in our midst. You need something stiffer than linguine for a spine...
