Daschle wasn't properly vetted by the Obama campaign (in part because he "forgot" to tell them about the chauffeur issue).
It's more than just taxes for the chauffeur now. According to the
Wall Street Journal, Daschle took impermissible charitable deductions, "forgot" to pay taxes on some consulting income, and there are questions about whether some entertainment and travel services provided by EduCap and companies should have been reported.
Daschle appears to be a major tax cheat who looks Geithner look good by comparison. But the comfy Senate club will still confirm him.
