I'm not sure this is relevant. As far as I know, he didn't come to power by a coup. Sure, there were lots of backroom machinations, his party didn't get outright majority, he exploited some pilitical stalemate, etc, etc, but it was all within the rules. All democracies have complex rules, the fact that he was appointed by someone else is a technicallity. For example, the 538 blog explained the other day that some candidate from Utah, unknown to the vast majority of the US voters, can technically end up president. Does that make the US not a democracy?
