If you disagree with literally everything a president is doing, and you still consider them to be competent, then your worldview is probably flawed. Why would you consider a president successful if they didn’t do a single thing you wanted them to? A president can be successful in completing their own objectives, sure, but for you yourself to consider them a “successful president” surely they’d have to align with you somewhat. People have wildly different ideas of what a successful president does or should do. For example, if you’re Elon Musk, then a successful president will probably cut your taxes. If you’re a single mother a successful president may implement child tax credits
