Senate Majority Leader Mitch McConnell made it official Tuesday: He’s calling House Speaker Nancy Pelosi’s bluff, and refusing to guarantee impeachment trial procedures of her choosing.

Pelosi’s been “threatening” not to send the House-passed articles of impeachment against President Trump to the Senate, triggering the trial, unless McConnell promised to meet her preconditions for a “fair trial.”

Specifically, she wants the Senate to hear from four witnesses the House didn’t bother questioning, because it would take too long to get court rulings compelling their testimony.

But the Senate chief has instead announced that he has the votes to adopt the same rules the Senate passed (unanimously) for President Bill Clinton’s impeachment trial in 1999. These will give each side the chance to make its case and face questions — then let the Senate decide if it needs new information, including any witness testimony.

Barring some dramatic development, Pelosi was always doomed to failure here. One problem was the blatant, politically driven contradiction between her rush to a House vote on impeachment and her subsequent delay of any Senate trial. Another was that both the House and Senate are jealous of their privileges — neither will take orders from the other.

Above all, McConnell has no need to hold a trial — if the House decides to blink by not sending over its articles of impeachment, it’ll only be that much more obvious that it never had a serious case.

Trump-haters are still in denial on all this, pretending that McConnell will “have” to bend because of minor developments such as former National Security Adviser John Bolton’s announcement Monday that he’ll testify if the Senate calls.

In reality, Bolton’s statement was far from earth-shattering: He didn’t, for example, say he’d ignore all issues of executive privilege from the president and answer every question asked.

Bottom line: McConnell’s made it plain he’s not budging; Pelosi needs to send the articles over or admit she’s not going to. Congress needs to get past this pointless impeachment distraction and get back to regular business.
