George, I agree that Daniel 2:20 means that God removes and establishes kings, but I don't think you can prove that in the case of the American election He has "done it for our judgment." God has not said plainly what His motives are, though we surely ought to trust Him that He does have them and that they are just.
I also question whether you should say "we have the leadership that we deserve." A lot of folk are going to suffer (and those now suffering will continue to suffer) the consequences of the President's bad policies, and few of them deserve it. Christians should be praying for wisdom as to how to help all the needy people who are going to be hurting and bitterly so during this bleak future period. Peace, Larry
