People who say that theory are crazy. Democrat are not going to go out of their way to get Harris ten years in office. No one wants that, except maybe Harris.
They went out of their way to put Biden/Harris in the Oval Office. They committed voter fraud to do it. Didn't even try to hide it. It doesn't matter who the Democrats put in the White House, Kamala Harris or otherwise, because somebody else will be running the show any way. They've already proven that. Do you really believe that any Democrat that gets elected President after Biden will be allowed to think, and act for themselves? That's not going to happen anymore. Whoever or whatever is actually in charge will not relinquish that power, and the Democrats will never demand that they do, because then they'd have to admit the 2020 election was fraudulent.
