I’ve written already about why I believe President Obama deserves to have his Supreme Court appointment considered by the U.S. Senate.

It’s his prerogative to appoint someone; it’s the Senate’s prerogative to approve or reject it. The Constitution lays it out there. I understand the idea of “advise and consent.”

If senators object, then they should say so on the record. The idea of obstructing a nomination by refusing to consider it is offensive on its face … at least in my view.

The president today nominated D.C. Circuit Court chief judge Merrick Garland to the high court, replacing the late Antonin Scalia.

The politics of this fight overshadows everything else. It overshadows Garland’s impeccable credentials, his immense standing among legal scholars, his compelling personal story.

Scalia was the court’s leading conservative voice. He was an ideologue. Garland is a moderate. He’s known to be a non-ideologue, but according to conservatives, well, that makes him a flaming liberal.

The court’s balance would shift with Garland joining the court.

And that’s why the Senate Republican leadership is vowing to block the nomination by refusing even to consider it. The GOP won’t even allow a hearing. Hell, GOP senators say they won’t even meet with Garland.

The Republican leadership that says it wants the next president to make the appointment.

What happens, though, if the next president happens to be, oh, Hillary Rodham Clinton? Are they then willing to put this selection in the hands of a president who could appoint a true-life flaming liberal? Or should they give Merrick Garland the hearing he deserves and cut their losses?

Garland’s intelligence and legal knowledge are beyond reproach. Even Republicans said as much when they approved his nomination to the D.C. Circuit Court. If he’s as smart and scholarly now as he was then, it makes sense — or so it seems — that he’d be a fitting choice for the Supreme Court.

The fight has been joined.

Senate Majority Leader Mitch McConnell said the people should have a say in filling this court seat. Mr. Leader, the people have spoken on it — by re-electing Barack Obama as president of the United States.
