It seems that he has upset his opposition so much that they have ganged up on him. It seems none of their Presidents have survives a full term. Opposition looks to be 2 representatives of a Muslim group, one a lady who has been locked up for corruption then a progressive, people's party type leader. Kahn may have tried to do something about corruption. Disappearing people figures but don't appear to be put down to Khan.
Macron would be the first to achieve a 2nd term for 20years and it seems few did before that.
Hungary's Putin's friend was re elected. The EU take a dim view of their electoral system. There opposition used the friend aspect as propaganda. All opponents may have ganged up by telling supporters to vote for one person. The idea seems to have caught on in France too - vote for Le Penn not me.
Oz's leader looks to be in trouble. His political plug is that they never said they were perfect. When he was elected last time some pundits were surprised as they thought he had wrecked their economy. LOL Gluten's for punishment as per the UK but ours did have a good lever to use. Not sure if Oz has anything to get out of. Nothing like the EU anyway.
