As for inheriting problems, he should note that Obama’s inheritance, politically, goes back to Carter’s administration.

Seriously, democratic practices or not, for the top job, which has responsibilities for not only leading a nation, but, in the case of the US, the world, I would suggest a thorough assessment of candidates before they qualify to run for office.
The cost of, inadvertently, electing an incompetent or even an ‘insane’ President or VP, as far as the US is concerned, is just way too high.
Democracy is an ideal, running a country at all levels, and significantly influencing the international scene are realities.
had done = has done
