It could also force Obama to veto a lot of legislation.
Which 9 Democrats are going to pass legislation Obama would be forced to veto?
Remember this Senate (probably) no longer has Baucus, Begich, Landrieu, Hagan, Pryor, etc.
Presumably, the 9 most conservative Dems still around would be:
Manchin, Donnelly, McCaskill, Heitkamp, Tester, Warner, King, Casey, and Heinrich.
I think a President Obama in his last two years, desperate to do anything really, is going to go ahead and pass any law Martin Heinrich approves.
If Majority Leader McConnell nuked the filibuster on legislation, I would blow the guy in celebration.
