I will support the republican nominee whoever it is, because they are all hawks and the dems are all defeatists, and that is what counts for me (and I might add, for the country, in history, etc).
But if someone once calling you names in a fight over one issue means you don't care if you get your way on that issue, you still will never work with them on anything ever again - then why not take up knitting? Because politics will never be your game.
