Nixon had 4 appointments in his first term (one because of Abe Fortas resigning). FDR had five appointments during his second term.
You are correct of course, but in recent history other than Nixon - have not seen or imagined it in my lifetime. I had a class in college on the history of SCOTUS. It has become far more divided in the three decades since and many of the cases it hears today were unimaginable when I was in college (prayer at a football game? - transgender training for kids - etc etc).
It is not possible to overstate the importance of SCOTUS appointments for a Presidential legacy and influencing the future. In some ways, it is the most important thing a President does IMO.
I would love for him to have 4 - especially the ones we expect. I could see Thomas retiring during Trump’s first term. Can’t wait to see the arguments from the left that Trump has to appoint a liberal to replace a liberal..... you know they will scream and chant this.
Nixon’s had to get his through a far left senate. He only got one conservative, with one moderate conservative, one moderate liberal and one extreme leftist, who wrote Roe vs Wade.
