Loyalty is a principle, and of high and ancient reputation. The problem is what do you do when two or more principles conflict? You can make anybody look like an idiot by focusing on one principle to the exclusion of all others. But that's not real life. Sarah is an exceptional thinker, and I believe she resolved those conflicts as well as anybody could in her situation, and in a manner vastly superior to Obama, and as well as or better than anyone among the GOP presidential contenders. She would have been a fine President, and I am sorry she is not running.
Supporting McCain over a true conservative hurts the nation.
