It sounds like if Trump wins, you plan to join the Hillary or Sanders campaign. I am sure they would welcome your wise counsel.
I'll be sure to vote for Pat Toomey for Senate. That's a vitally important race, and ample reason for me not to stay home.
It seems to me that your view of the situation is fringe and emotional in the extreme. If you plan to leave the Republican party if Trump wins, you should start packing your bags now. I am sure the rest of us will miss you, but will do just fine without you.
I will not support a demagogue. You will. You say I'm emotional. I say I have self-respect.
Perhaps, and this is just a theory, it is not the 40 - 50% who support Trump who should run Independent. Maybe it is you who is in the wrong party? You certainly are not with the mainstream flow of the Republican base. That is shown in every poll.
If the Republican base embraces Trumpism, you are absolutely correct. I will then be in the wrong party. A party that let itself get hoodwinked into selling its soul.
