“If we were engaged in a war,” said he, “and were to choose a general, would we make choice of a man given to wine or women, and who could not support fatigues and hardships? Could we believe that such a commander would be capable to defend us and to conquer our enemies? Or if we were lying on our deathbed, and were to appoint a guardian and tutor for our children, to take care to instruct our sons in the principles of virtue, to breed up our daughters in the paths of honour and to be faithful in the management of their fortunes, should we think a debauched person fit for that employment? Would we trust our flocks and our granaries in the hands of a drunkard? Would we rely upon him for the conduct of any enterprise; and, in short, if a present were made us of such a slave, should we not make it a difficulty to accept him?-The Memorable Thoughts of Socrates by Xenophon
I'm not sure how I feel about morally corrupt politicians in positions of federal power. My libertarian husband says that you cannot dictate morality, yet he also says that all politicians are corrupt and not to be trusted, and that he would rather vote for a Democrat with moral integrity than a Republican without it. My philosophy has always been that I care little about somebody's personal life unless it interferes with their job, especially lawmaking. Sexual sin can definitely be distracting if you're any kind of professional, but only since feminism, abortion, gay marriage, and invasive airport screening has sexuality itself become a national issue (of course, for the sole purpose of grooming the people to treat it as something deserving of federal legislation).
So what about politicians who cheat on their wives? I must admit that when the whole thing about Gingrich came out, it didn't bother me as much that he had had a third wife as a result of an affair than it did that he, a rich man having been entrusted with a large salary by his service in Congress, couldn't manage his own money. To me, there's a lot more danger in having a Congressman or President with no financial integrity than it is to have one without sexual integrity, wherein he only harms himself and his family, not an entire country—even though that is changing.
That, I think, is how I feel about corrupt politicians in positions of federal power.
UPDATE: The news story of today is of the impeachment of Governor of Illinois Rod R. Blagojevich, who was found guilty of 17 out of the 20 counts of corruption, including trying to sell the Senate seat vacated by Barack Obama in 2008. Blagojevich is the 6th out of the 14 Illinois governors since 1913 to be sent to jail.
