Nah, it's really just Republicans doing all the corruption these days at the SUpreme Court. Unless you can provide some decent examples of Democrats. You seem to be bothsidesing the issue when McConnell stole multiple seats.
Clarence Thomas was confirmed in a very different era of politics, when the long term right wing strategy was only just beginning to take root; the vituperative rhetoric was still on the comparative fringe of talk radio; and cooperation was still the norm from both sides.
Obama should have picked a replacement for RBG. Biden and the democratic congress should have done more to get the judiciary back in line. They had their opportunities.
RBG passed away while Trump was president. Obama did pick a replacement for Antonin Scalia though: Merrick Garland. Republican Majority Leader Mitch McConnell refused to even give Garland a hearing arguing it was "too close to the presidential election", even though Obama's term had about one year to go.
