The best and the brightest (and their tax problems)

It is hard to keep up with all of the tax problems of Obama nominees, so here is a quick summary, in no particular order:

1. Health and Human Services nominee Kathleen Sebelius: $7,000 in back taxes.
2. Health and Human Services nominee (and former Senate Democratic leader) Tom Daschle: $140,000 in taxes and interest.  (Since it was disclosed that he failed to pay taxes on his limo and driver, it is fun to go watch this Tom Daschle campaign commercial.)
   
3. Treasury Secy. Timothy Geithner: $34,000 in back taxes.  Now confirmed and in office, he intends to pursue tax evaders.
   
4. Nancy Kelleher had been Obama's choice to oversee budget and spending reform:   failed, for nearly two years, to pay employment taxes on household help.
5. Labor Secretary Hilda Solis: her husband had tax liens against his business that had been outstanding for "as long as 16 years" that were settled (or partly settled?) for $6,400.
   

Does the IRS normally charge penalties in cases like these?  These Democrats didn't seem to have paid any.

Separately, New Mexico Gov. Bill Richardson "announced he no longer wanted the
Commerce Secretary job because he had become the focus of an ethics
probe looking involving state contracts."

PREVIOUSLY, tax problems of Rep. Rangel, former Sen. Wellstone, and possible senator Al Franken were discussed here.  Polls showing that Democrats think it is OK to cheat on taxes are discussed here.  Clinton Attorney General nominees Zoe Baird and KimbaM. Wood also had tax problems.
