Go ahead, confirm it's nonsense. Then from the political point of view, Barret really makes the court 5-4. (Noting John Roberts actual record).
Nothing new here, it's been 5-4 conservative many times.
I laugh at anyone who claim that John Roberts is a conservative. He may not be as liberal as Ginsburg or Sotomayor or Kagan, but he is definitely not a conservative. In 100% of the crucial judgements, he has sided with the left. Perhaps the media want to paint him as a conservative, since he was appointed by George W. Bush.
Trump is perhaps the only Republican president in the recent times who have nominated 3 "real" conservative judges (Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett).
George W. Bush, during his two terms nominated one each from the liberal and conservative spectrum (John Roberts and Samuel Alito respectively). The same was the case with George H. W. Bush. He also nominated one each from the liberal and conservative camps (David Souter and Clarence Thomas). Similarly, Ronald Reagan got to nominate 4 judges to the SCOTUS, and he also picked two each from both the camps (liberals - Sandra Day O'Connor and Anthony Kennedy, conservatives - Antonin Scalia and William Rehnquist).
What makes Donald Trump different from all the other GOP presidents before him is the fact that he refused the temptation of becoming the media's darling by sticking to the conservative nominees. This is something none of the GOP presidents before him could do.
