Alice laughed. "There's no use trying," she said: "one can't believe impossible things."
"I daresay you haven't had much practice," said the Queen. "When I was your age, I always did it for half-an-hour a day. Why, sometimes I've believed as many as six impossible things before breakfast."
1. One can support a candidate, without supporting all of their positions. One can even criticize a candidate and support them at the same time.
2. One can support a candidate, without believing all other candidates are evil, stupid, co-opted, or feckless. One can even like and respect a candidate but still not support their candidacy.
3. One can support a candidate and still respect the choices and beliefs of friends and allies who support a different candidate. It is possible to continue to learn from people who have not reached the same conclusion that you have.
4. One can engage in vigorous and respectful debate without resorting to personal attack, or suspecting the motives, patriotism, or humanity of people who hold opposing opinions.
5. For every thing there is a season. A time to be divided and a time to be united. Make the most of this time of division, but be ready to move on when the season changes.
6. Regardless of who wins the nomination, the world is not going to end this year or the next. If the candidate you support wins, they will almost certainly disappoint you in some ways. If the candidate you support loses, the winner will almost certainly surprise you in some ways.
