Apparently not paying taxes you are fully aware you owe is not a disqualifying factor for running the IRS, but owing over $100,000 is just too much.
IMHO, Geithner should not have been appointed to run Treasury if he couldn't figure out how to comply with IRS rules that he had clearly been informed of. At least Daschle had the defense of working in a somewhat murky area of tax law.
So far President Obama seems to be doing well, but he should toss these nominees the minute he finds out they have problems. It makes him look like he's running an administration that allows different rules for the elites; something he did not campaign as representing.
