“If President Trump were still in office, I would have carefully considered whether the House managers proved their specific charge,” he said. “But in this case, that question is moot. Because former President Trump is constitutionally not eligible for conviction.”

That’s McConnell explaining that he didn’t vote for conviction, because Trump’s term was over at the time of the vote. Not because the case was “weak” – you can find video of McConnell speaking his agreement with the charge.

Impeachment is clearly impossible in this climate.
