whether Biden or Trump wins, nothing will noticeably change.
Sure, Biden and/or Trump are both demonstrably
unnecessary to keep the country running from day to day. The office of the presidency is a mechanism utilized by the "president's people" as well as embedded career bureaucrats ("the deep state") to perform the functions of the executive branch while pursuing political and personal goals.
Appointees and elected officials alike, regardless of party, tend to answer to vested interests, and can often switch back and forth between answering to those interests while in office and representing them as lobbyists.
It's going a bit far to suggest that Trump's election has been inconsequential, and things would have played out the same way if Clinton had won. For better or worse, things would at least be different.
Someone other than Gorsuch would have replaced Scalia, and Kennedy would not have retired to clear the way for Kavanaugh.
Let's say Clinton serves one term and isn't allowed to replace Ginsburg. Okay. Let's put Gorsuch in there. Breyer doesn't retire but Kennedy does. Let's put Kavanaugh in.
In June 2022, Alito, Kavanaugh, Gorsuch, and Thomas vote to overturn Roe v. Wade, while Breyer, Sotomayor, Kagan, Roberts, and Hosni Mubarak vote to keep it intact.
That's different. Hosni Mubarak is still alive.
