Matthew Walther at The Week argues that no smoking gun has been found to support the claim that the Trump campaign colluded with Russia in its interference in the 2016 presidential election.

Walther (isn’t that the name of a gun manufacturer?) wanders a little, asserting that when the Clintons fly first-class for their global charity, they reveal their corruption, and so justify ongoing support for the President. I find that argument weakened, however, in that Trump flies in a private jet purchased with funds gained laundering money stolen by Russian kleptocrats.

And as for the central assertion: it’s going to be awfully hard to find a smoking gun in the radioactive crater left by the hydrogen bomb Trump has set off in American foreign policy. As Rachel Maddow has been laying out, Russia has been given everything that it could have asked for. Trump’s craven catering to a murderous tyrant is all the evidence required to prove his unfitness to be our head of state.

Or should that have been “cave-in cratering?”
