"Ugh. If Hillary is the candidate, I won't vote.
I don't want any of those crazy Republican candidates anywhere near the White House (and all of them are many times worse than G.W. Bush)."
Agreed.
In which case you'll need to vote.
A significant number of us have never voted 'for' anyone, only against.
A significant number of us are pragmatists who long ago accepted a fundamental fact of American politics: voting for the lesser of two evils.
It's understood that there are those who wish to feel excited about those whom they vote for, that their vote will make a difference, and will go to support a candidate who will accomplish what the voter would like to see accomplished.
But that's often not how it works.
The problem isn't a lack of 'good' candidates, or that 'poor' candidates alone seek public office.
The problem is the hyper-partisan nature of American politics, where not only elected office and its privileges are at stake, but where our fundamental rights are in jeopardy, part of the spoils of political war, the consequence of those crazy Republicans, rightwing extremists, and social conservatives.
The Framers created a Constitutional Republic to safeguard our rights and liberties, to shield them from the intrigues and acrimony of partisan conflict, from those who would seek to attack the protected liberties of their political enemies, as most on the right seek to do today.
It would be nice to participate in the political process, to support the candidate who best represents one's views and beliefs, comforted by the fact that whomever might become president, one's rights and liberties would indeed be beyond the reach of that partisan conflict.
Sadly, that's not the case.
With each of the republican candidates for president hostile to the privacy rights of women and the equal protection rights of gay Americans, who as president would appoint judges to the Federal courts and justices to the Supreme Court with the intent of undermining settled, accepted Constitutional jurisprudence and our protected liberties, in addition to republicans' wrongheaded fiscal policy, foreign policy, and propensity for war, we are compelled to vote this November, to vote against the republican nominee, not 'for' someone we don't like.
