Taxes probably get very complicated for guys at the level of Tom Daschle. But that's why you pay accountants and lawyers, to keep this stuff in line for you.
He's one of three who've been appointed to various spots in the Obama administration who've had troubles with taxes. At some point you have to say this is ridiculous stuff. Didn't we hear how vetted all these people were supposed to be? I know I looked at the application for jobs to the administration and it had various things you were supposed to disclose.
I definitely wouldn't want to be a guy at a high level like Daschle, then they find out a month after nominating me that I didn't disclose something very pertinent ... like I didn't pay my taxes! For crying out loud.
