You feed the beast of what it loves: Delicious hyperbole.
The next president may choose as many as 3 justices, one ultra-conservative (Scalia) for sure and a few of one ultra-liberal (Ginsberg), one liberal (Breyer), and and one swing vote (Kennedy). Their appointees will play a role in the future of the country, but just a role. A vote for Hillary only really flips Scalia, who should have been flipped by Obama if the Senate had deigned to do its job.
Don't worry: The Constitution-respecting Senate are setting up both parties to not approve any nominee by any president based on the precedent of "nah nah boo boo we don't have to do anything."
