In which I do not endorse a presidential candidate

So I usually don't talk about politics here. And for the moment, this blog will refrain from endorsing a presidential candidate. This is mainly because I haven't thought too hard about the presidential elections, because the Pennsylvania primary isn't until April and the nominations will probably be decided by then; the election that really matters for me is the general election, and I don't want to get too attached to a particular candidate right now since they may not be in the general election. (Here's an interesting interview with William Poundstone on different methods of voting, via Slashdot.)

But it occurs to me that one thing that we should be against in a presidential candidate is pigheadedness of the sort that George W. "Stay The Course" Bush has shown. New information becomes available, and this is something that any presidential candidate -- well, really any president -- should take into account. They should not become wedded to their positions if new information becomes available. (By the way, I'm not saying that I want a president who decides what to do based on opinion polling that tells them whether they'll be able to keep their jobs. I want someone with principles -- but these principles should include a willingness to change their mind.) I don't want to go so far as to say "path-dependence is the scourge of history", but I'll say it inside quotes.
