He's not senile, his body is frail. But he's never been sharp as a whip, even when younger....there were always others much much sharper, like Hillary! Though he has been a steady rudder....as President.... His wisdom from being in government and knowing how it functions is now an advantage.
Trump just wants to blow up the Constitution, law enforcement, our judicial system, our military, our intelligence agencies, all Treaties, all norms, all ethics, standards, our Rules, and anything else he gets his hands on, like our entire Nation! I'll pass on that!
Even with its faults, I love my country and don't hate it with a passion, like Trumpers seem to.....
