McConnell was given the power to do that by the rest of the Senators who put him in that position. The narrative that Garland would have been confirmed if only he’d gotten a vote assumes that McConnell didn’t have the support of his caucus in what he did. That’s an incorrect assumption. They could have removed him and done what they wanted to do if there was some groundswell of support for Garland in the Republican Party. There wasn’t, they supported McConnell, and Garland wasn’t brought to a vote. That’s just how politics works.
