I am sure you are right and that a lot of people will support whoever is the President after the next election simply because he is the President. I am sure that a lot of Democrats did exactly that after the 2000 election at least up to 9/11 and some months beyond, although obviously there were also a lot who didn't.

But there is a problem, isn't there? My President, right or wrong? Or, since I'm in the UK, my Prime Minister, right or wrong? I can't go along with that one, I'm afraid. I don't think there is anything to be gained by simple abuse, but where a leadership has behaved in a way that you regard as seriously flawed or worse, don't you have a duty to criticise it, rather than simply say they are doing their best?
