#NeverTrump has always meant different things to different conservatives. But the proximity of the Republican convention is bringing a key division within the campaign to stop Trump into sharp focus.

That division is between those who believe Trump should be denied the presidency, and those who believe Trump should be denied the GOP nomination altogether; it’s between those who recognize that Trump has forced the party to confront massive problems before it can responsibly stand for the presidency again, and those who seem to believe everything in the Republican Party was fine until Trump came along.

For the purposes of handicapping the coming election, the distinction is unimportant. As weak a candidate as Trump is proving to be, any not-Trump alternative who emerged from the convention as the nominee would be similarly weak, weighed down by a perception of illegitimacy among Trump supporters and other Republican voters.

But for the purposes of gaining insight into the right’s assessment of its own health, the schism matters a great deal.

This past spring, when defeating Trump was still mathematically possible, #NeverTrump was a worthy endeavor, intended to convince Republican voters not to make a grievous mistake. After having failed to convince those voters, and then failed to convince GOP leaders—like RNC chairman Reince Priebus, and House Speaker Paul Ryan, and Senate Majority Leader Mitch McConnell—to disclaim the winner of their primary, one #NeverTrump faction still believes the party should wrangle its way into power anyhow, despite the dysfunction Trump has revealed.
