I don't think claiming definitively that to this point there is nothing to the claims is quite the same logical stretch, but I get your point.
I think it's more of a Schrödinger's cat conundrum - with two sides debating the different possible fates of the cat. If the validity of the Russian collusion claims are analogous to the cat, my basic position is, if that pussy was ever alive we would have heard it make noise by now, and it's been in that box for like 9 months. So if it's not dead, I'm pretty sure the cat is more likely to be dead with every passing day. Stupid cat.
