If he doesn't provide evidence now within the next two weeks, more people should start seeing him as the fraud he is.
One would hope! Called to mind a NYT op-ed from Charles Blow:
Disciples of a False Prophet.
I am not sure I share his optimism, though. Sure, in a sensible world, people will say, "Darn, I guess I fell for that" and demand accuracy and accountability. In that world, though, Trump never comes close to securing the Republican nomination much less win the election.
We've been expecting every show of stunning incompetency to be the one that breaks this house of cards. Now, finally, we think at each turn, reason will win out.
There's another far more horrifying possibility, which is that Trump support is a bulwark immune to all semblance of reason. In this model of the world, when things go bad, his supporters redouble their faith. Reason will be crushed.
I don't know which model is correct. Before the election I would have believed the former. I'm worried that we by and large continue to discount the possibility of grave danger -- because indeed, what if it's our voices and not the Trump band's that gets discredited and snuffed out?
