This is absolutely amazing news!
I have always been a fan of Tom Daschle and was very upset when he became a casualty of the Bush administration's slash and burn approach to politics. They vilified Senator Daschle and impugned his name at every turn. Blaming him for undermining their plans by using filibusters to block confirmation of several of Bush's nominees to the federal judiciary. In other words they needed him out to do things like spy on Americans, get rid of habeas corpus, and use torture against enemy combatants. If Daschle had retained his seat you can bet all of that would have been a lot harder to accomplish.
Seeing him reinstated in such a prestigious position in this historic administration is very gratifying. And I know he will do an incredible job.
