LOL. Obama has a right to nominate anyone. Senate has a right to not confirm anyone.
The Senate has the right to deny any vote at their own political risk. But that is it! There is no obligation to confirm an appointee immediately and no statement in the constitution about the timeline of the Senate's obligation. And any insinuation that there is is simply hackary. Dems would be doing the same thing if an R was in office. Get over it.
If the GOP keeps the seat vacant all year, Democrats will see to it that the GOP pays in November 2016.
That's very optimistic of you.
Remember when the Republicans throwing a temper tantrum and shutting down the government was supposed to hurt them? Remember when the country despised Republicans for getting us into trillions of debt, destroying the economy, and starting endless wars, then turned to them as glorious saviors 2 years later?
