I have already decided that he gets no more votes from me, ever. If he is the Republican candidate for Senate next year, then I plan to vote for a conservative Senate candidate from some other party.
This is what I used to do with my children. If they were across the room and I told them to stop doing <whatever>, they had to stop it immediately to avoid getting a "swat". A number of times, they would keep on with it, just checking to see how serious I was. Once I moved to get up, they would immediately stop, but my rule was, "If I have to get up, it's too late."
It's too late for Lindsey.
I like your philosophy. I think I would also decline to vote for Graham. He got too cocky.
