Democrats gloat when they speak to House Minority Leader Kevin McCarthy about impeachment. “We know you’re losing because you keep talking about process,” they’re inclined to say if they bump into him at the gym. This suggests they’re convinced by that old wisdom about politicians not discussing process unless substance is against them.

But there’s an equally potent idea in politics that “when you’re explaining, you’re losing.” And Democrats have spent more than a month desperately explaining: explaining what’s wrong with President Trump prodding Ukraine to investigate Hunter Biden’s sleazy $600,000 stipend from a shady energy company, explaining why it was abuse of power, explaining how it undermined the “interagency consensus” — man, if ever an idea was less likely to alarm ordinary voters! — explaining why it amounted to bribery (the crime that, not coincidentally, Democrats decided on after poll testing it against other charges).
