Herol and Dino ... two fat, failed retired posters with the collective IQ of a cloud of gnats. Their sole existence is devoted to their hatred of Wlad. Frankly I would not be surprised if they were one and the same person. Or maybe HerolDino is an amoeba that fell onto a concrete floor and split in two? Regardless, without Wlad to hate they are less than nothing.
I had a feeling at the time that he knew that it was his last hurrah and that he was going to go all out to try and win it. Herol has a point that strictly on "merit" Sanders did not merit a shot at that point - however iirc he was like the tenth person Wlad's people contacted and the only one willing to fight on short notice. Just goes to show that he'd been avoided in his prime for a reason ...
