It is possible that by firing the non-elected ITTF CEO (reportedly one of Sharara's friends/cronies) and ending the marketing agreement with TMS, Weikert is signalling to to people who may be hesitating to vote for him that the Sharara days are now over. Perhaps in response to this, the third guy has removed himself from the running. So now (or so the thinking goes) there should be no reason for some of them to vote for Saive. I suspect this may be Weikert's way of just making sure there will be no surprises.
I would personally still prefer Saive just because of new blood etc., but anyway, this is what I suspect is going on. I could be wrong of course. I am not an insider, just someone who has observed for a long time.
Now, the optimistic hope is that with Sharara fully out of the picture the ITTF will stop doing so many dumb things. He was incredibly unpopular among pretty much all players for good reasons and you always had to ask the stupid vs. evil question where Sharara was concerned. Now with Weikert, maybe it is a question of meeting the new boss, same as the old boss, even if he has managed to have the old boss killed. (Metaphorically). But maybe with a clear electoral victory, he would be better. We will see in any case, and it's not like any of us get to vote.
By the way if Saive actually wins, I state here and now, in advance, that from that point forward, nobody should listen to anything I say about the ITTF. I will admit that I was not just wrong but badly and stupidly wrong and that the only thing anyone should listen to me about from that time forward is stuff I write about Viscaria blades, the weights of plastic balls, and biomedicine. Well and maybe the cuteness of Liu Shiwen.
