With Senate Democrats determined to slow the confirmation of President Donald Trump’s Supreme Court nominee, Brett Cavanaugh, on a wing and a prayer that they will retake the majority in November, public support of Judge Cavanaugh is critical to the process.

Senate Majority Leader Mitch McConnell, R-Ky., is equally determined to hold a confirmation vote before the high court begins a new term on October 1, and a letter supporting Kavanaugh signed by 31 state governors goes a long way toward making that goal a reality — except that four Republican governors have opted not to sign it, Fox News reported.

The four governors not willing to sign on that Kavanaugh’s “impeccable credentials demonstrate he is worthy of this nomination,” as the letter says, are from blue states and all are facing reelection this year.

Gov. Charlie Baker is one of the four GOP governors.

Hailing from the land of Sen. Elizabeth Warren, D-Mass., Baker has said abortion rights are important to him and that a Supreme Court nominee should rule in favor of pro-choice issues, according to Fox News — all of which undermines the concept of a judge ruling based on the merits of a case.

Another governor who has not signed the letter is Maryland Gov. Larry Hogan.

His Democratic opponent, Ben Jealous, the former head of the NAACP, has made the Kavanaugh nomination a campaign issue, calling on Hogan to oppose the pick, Fox News noted.

Illinois Gov. Bruce Rauner is a third Republican governor not to sign the letter.

Having previously said that he supports Kavanaugh, Rauner appears to be trying to walk a tightrope in the Land of Obama, formerly known as the Land of Lincoln.

“I believe he is highly experienced, well-qualified for the position, and I hope that his nomination is voted on and approved expeditiously,” Rauner told reporters early this month, according to the Chicago Sun-Times.

Rounding out the foursome is Vermont Gov. Phil Scott, from the state that gives us self-avowed democratic socialist Bernie Sanders.

In hindsight, the more remarkable aspect of the story may not be that these governors did not sign the letter, but that these Republicans managed to get elected at all.
