There is a lot of unreasonable discontent on both sides of the aisle.
Why is it unreasonable to not support someone you dislike?
"Unreasonable" might not be the right word... I just think that too many people are finding reason to hate their choices rather than striving to find things to like about them. Two of these individuals are going to be their respective party's nominee for President, and one of these individuals will be President. These are the choices, and not everyone is going to agree -- but the hate and vitriol, even within the parties, just seems out of order.
And I pledge to support the Republican nominee, provided it is any of the major candidates for the nomination.
