He was not "ousted", he simply left the country. At no time did he resign, nor new Kiev junta government took any steps to actually fire him in any way. They simply installed Poroshenko, well, after having "fair" elections. And 2 had Presidents at same time.

We also forget the first color revolution, back in the day, when they had "fair" elections to install Yuschenko (another one of L'vov nazis).

The place is so corrupted at this point I really have no idea who they can find that is not corrupted. The only 2 leaders who are not are those running new republics of Donetsk and Lugansk. The rest are all indebted and are pawns to one oligarch or another, Zelensky included.
