No, but here's a hint. Every bill that comes out of congress has to get past a Presidential veto. In most cases, the bills being filibustered by the minority Democrats during 2000-2006 were ones the White House supported (congressional Republicans have been lock-step with Bush throughout his presidency) whereas the bills blocked by minority Republicans in 2006-2008 are ones that the White House probably opposes.

Knowing that, which ones do you think were more objectionable?
