The word this morning is that President Obama might reveal his selection for the U.S. Supreme Court as early as, oh, Monday!

Excellent. Let’s get this going-away party for the president started.

He reportedly has narrowed the field to three men. One is an African-American, one is an Indian-American, one is a Caucasian. They’re all reportedly able individuals who’ve been confirmed to spots on lower federal appellate courts. The president said he’s going to consider someone whose credentials are impeccable. Moreover, he appears to be zeroing in on someone who’s already passed GOP muster in the Senate.

But, hey. Hold on. Republicans who control the Senate — which must approve the nominee — say they ain’t budging in their refusal to even consider an Obama selection. They want to wait until after the November election.

Here’s where it might get dicey for the Republican leadership in the Senate that is digging in its heels and refusing to do its job — which is to consider and decide whether to confirm a Supreme Court nomination.

Suppose the Republican nominee is Donald J. Trump, who the GOP “establishment” despises. Suppose the Democrats nominate Hillary Rodham Clinton, who the GOP despises perhaps even more.

Suppose, too, that Clinton wins the election in November. Suppose she wins big, as in really, really big.

Do the Republicans believe they’re going to get a more suitable nominee from a President Clinton than they would from the current president? After all, the next justice is going to replace the iconic conservative jurist Antonin Scalia, who died a month ago while on a hunting trip in West Texas.

The balance of the court is likely to change, meaning that the appointment is, shall we say, h-u-u-u-u-u-u-ge!

We might know a thing or two about how this shakes out on Tuesday, when voters in five states decide in primary elections in both parties. Clinton might be able to tighten her vise grip on the Democratic nomination. And Trump could establish himself even more firmly as the GOP frontrunner.

So, with a Clinton-Trump contest shaping up in the fall — and with Republican power brokers scared spitless at the prospect of their party being led by a demagogic know-nothing blowhard — the GOP might want to rethink its resistance to whomever Barack Obama selects for the nation’s highest court.

As someone said this morning on one of those Sunday news talk shows, it might be better to “deal with the devil you know than the one you don’t.”

Let’s all stay tuned. This week well could shake the political ground under our feet.
