I was reminded today by one of the blogs I follow that whomever wins the election has a good chance of appointing 2 or possibly three new Supreme Court justices. Thomas and Alito are both in their 70s (75 and 73) and will likely retire if Trump takes office.
Sotomayor is 69 and is rumored to have health problems, it's likely she may resign right after the election to allow Biden to rush her replacement thru the Senate while there's still a slight majority.
A bit of a wildcard is Roberts who is also 69. He's likely to just say the hell with it within the next 4 years. That would actually make 4, though I think he may try to stick it out.
A Trump victory and Roberts retirement would likely mean that he would get to appoint 7 of the nine justices. Most of them young enough to stick around for the next 15-20 years.
Definitely a frightening prospect
