The thing is, as horrible as it is, he's won. The tricks he's pulled between the last year of Obama's premiership and today have all ultimately succeeded. ACB is going to get through and the court will have a Republican supermajority for years if not decades. That is HUGE. While presidential races are exciting and engaging, the winners' terms last for years - judges, who realistically hold more soft power, are in place for decades. No Democrat legislation that is even remotely controversial (ACA, for one) is going to get past the Supreme Court, and any regressive Republican laws, when we next have a Republican president, will get ushered through. The Republicans are in for a bad few election cycles politically I think - demographic changes are really threatening them in some historically red states, like Texas - but it ultimately won't really matter now they have the court.
Graham may be a man without principle, but he's basically secured an America built on his (or, more accurately, I imagine, his funders') principles for decades.
