Let me ask you this.
If the democrats were the one fighting the Iran deal, would they just give up? Hell no. They would use every trick in the book to fight and fight and fight.
If the Republicans fight with no compromise they will win this. They need to be ferocious and show they will not give an inch and they will win. The majority of the country will rally behind them.
"What? Over? Did you say "over"? Nothing is over until we decide it is! Was it over when the Germans bombed Pearl Harbor? Hell no! "
