The major problem - one of the many major problems with governing people is that of who you get to do it; or rather of who manages to get people to let them do it to them. To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.
Tired of it yet? Me too. However, when the RNC says "President Bush volunteered for duty in Vietnam, but wasn't chosen," I feel compelled to help everyone understand it's a 100% lie.
