I have been following the impeachment hearings with a lot of interest. It is shown live over here and my confinement gives me a lot of spare time. My understanding of it all is that it boils down to the limits of Presidential power and whether Trump breached those powers in pursuit of personal objectives. The left seem to think he has clearly done so but the right do not seem keen to grapple with that issue and are focussing on discrediting the witnesses. My question relates to where the line is drawn. Is a President able to act like a King in pursuing any policy he sees fit ? Or is he bound by constitutional constraints that make him accountable? As an example - If a President offered aid to a country in return for favours to a business he had an interest in. We could all agree that it wd be an abuse of power. But if a President asked a leader to deal with corruption in his own country as a condition of aid then that would be legitimate. So where does Trumps behaviour fit between these two extremes?
