I don't think it's fair to compare your wife to a politician. People want to hear the candidates spout the stance of their interest group. Talking to many different groups to garner support will necessitate saying conflicting things, sometimes referred to as lies. Politicians feel they must lie to succeed. So you have a profession that demands skilled liars. Wives on the other hand don't need to lie. So saying you how you would judge a politician who you know lies and cheats is not the same as saying how you would judge a wife or a husband who lies and cheats. At least it isn't the same to me.
