I am asking for mothers to stop these lawmakers at the grocery store and tell them: You’ve lost my vote. I am asking activists to unsubscribe from these senators’ e-mail lists and to stop giving them money. I’m asking citizens to go to their offices and say: You’ve disappointed me, and there will be consequences. [...]
