This was NEVER about federal regulation or bans it was all a signal for the states to do what Congress cannot. Feinstein's bill was DOA from day one but every swinging d$&k liberal in every state house is rushing to pass anti gun laws in an attempt to overwhelm the opposition. Once Congress passes a law it goes straight to SCOTUS, no lower courts required...state laws must go through the state and circuit courts first, a long and expensive process.
Ms Feinstein is disappointed. She will go back and tell her people that she tried to get it through. They will tell her that they are "sorry to hear that, but we'll keep you in office next time so you can try again".
Cruz will say "I prevailed!", his people will say "Good, We'll keep you in office."
Meanwhile that debt continues to rise, foreign relations continue to suck, unemployment is still high, taxes are going up.
God Bless Senator Grassley for fighting the good fight. He is one of the FEW senators that refuse to back any of the knee jerk legislation that seems to be running rampant these days. I have met with him on a few occasions ( he has town hall meetings in EACH of the 99 counties in Iowa at least once a year) and is pro 2A. Check out his questioning on Fast and Furious.
