Advise and consent is in the Constitution and that little rule you mentioned goes back over 200 years. How does the Senate have any influence on a president without the minority having some sort of power to halt a very bad nomination. Jefferson put this in place to force a president to make more mainstream nominations and not partisan cookie cutter appointments. Like the right to privacy, this is a constitutional protection even without being in the Constitution.
Funny that in 2005 Reid, Biden, Feinstein, Clinton, and Obama (running for the office) were absolutely against the "nuclear" option as threatened by the GOP (but never carried out).

And you are correct. The dems did say they were against the Nuclear option, as do all parties out of power. But even they didn't obstruct Bush to this level. They did, but it wasn't nearly like it is today.
