It wouldn't surprise me if he pulls a Putin/Erdogan to wait out the required break, but I'm mainly talking about him teaming up with the commies to rig the parliamentary elections, and he's allowed to call another one this summer if he wants to (the parliament has to sit for a year before it can be dissolved). It's not like a new (non-FN) president would behave any differently anyway. Dirty tricks to lock the Right out of power are very much the norm in European politics.
