Honest mistakes?!

So, Obama appointed Timothy Geithner to lead the Treasury Department. His credentials suggest he's qualified. However, now it was reported in USAToday that he didn't pay his taxes in 2001, 2002, 2003 or 2004. Now maybe he paid taxes in those years, but he certainly didn't do it correctly. Now, he has paid his back taxes and an interest fine on top of that, but people in Congress (Democrats) are calling it an honest mistake and saying it shouldn't affect his confirmation. First, I suspect if it were a Republican President who appointed such a person to office, Congress (both Dems and Reps) would be up in arms, but for some reason, since Obama appointed him, it seems it is just an honest mistake. Okay, I'm not saying he belongs in jail because he did pay his back taxes, fines and interest. Of course, I'm wondering what happened to the days when we put people in jail for tax evasion. Nonetheless, my point is this. For someone who is supposedly qualified to run the Department of the Treasury, this is a problem, for someone appointed to almost any other position in the cabinet, this can be called an "honest mistake". You see, he didn't make a mistake in his taxes for one year, which anybody can do. He consistently made the same mistake in his taxes for four years running. Only a 2006 audit caught him. If it hadn't been for the audit, would he have ever paid his back taxes? You could argue that a person could make the same mistake over and over again if they didn't know it was a mistake, and I'd agree. However, I would never argue that that person is also qualified to run the Department of the Treasury, so no, I don't buy that he just made the same mistake over and over. If he is qualified to run the Treasury, then he should have known better, otherwise, he either isn't really qualified or he is a crook. Oh wait! Nevertheless, one other issue has also come to light. It seems that mister Geithner hired himself a domestic worker in 2005. This person was supposedly legal when they were hired but overstayed their time and worked illegally for Mr. Geithner for three months. Now, assuming the facts here are correct, I'd call this one an honest mistake. Anyone can hire a worker who is legal and not pay close enough attention to when their visa expires, I can see that happening. It certainly wouldn't disqualify him from serving as Treasury Secretary. If he wanted to run the Justice Department or immigration services or Homeland Security then I'd argue it is more than just an honest mistake, but he isn't being asked to run any of these agencies. So, my conclusion is that this pick should step aside, not because he hired an illegal, but because he apparently isn't qualified to do his own taxes, much less run the Treasury Department.
