Update: Grassley and McConnell have at last accepted Obama’s invitation to discuss potential nominees at the White House, although they are still refusing to hold hearings or a vote on any potential nominee.

As Senate Republicans close ranks in an attempt to prevent President Obama from nominating the next Supreme Court justice, Republicans on the Senate Judiciary Committee have declared that they will refuse to hold a hearing on Obama’s nominee, no matter who it is. On top of that, the Des Moines Register reports that the committee’s chairman, Sen. Chuck Grassley of Iowa, hasn’t even responded to an invitation from the White House to discuss possible nominees.

The Republicans’ unprecedented Supreme Court blockade exposes the lie that has undergirded eight years of GOP obstructionism: that President Obama is “the most divisive” president in history and that he refuses to reach across the aisle.

Senate Majority Leader Mitch McConnell, who just an hour after the news broke of the death of Justice Antonin Scalia, made it clear that he didn’t intend to consider any Obama nominee to fill Scalia’s seat, has called Obama the “most divisive” president he’s worked with. Marco Rubio, the Florida Republican senator and presidential candidate, has said that Obama is the most “divisive” political figure in modern history. The claim has been repeated over and over again in talk radio and the halls of Congress. Texas Republican senator and presidential candidate Ted Cruz complained after Obama’s final State of the Union address last month that the president “lectures us on civility yet has been one of the most divisive presidents in American history.”

As Paul Waldman wrote in “The Week” last month, the primary example of the “divisive” Obama that Republicans point to is that he “crammed ObamaCare down our throats” — a strange way to explain a bill that became law through the legislative process.

Waldman noted:

Let’s just remind ourselves of how Republicans have treated Obama over his seven years in office, with a few of the greatest hits. You can start right on the day of his inauguration, when congressional Republicans gathered for a dinner at which they decided that rather than seek areas of cooperation with the new president, they would employ a strategy of maximum confrontation and obstruction in order to deny him any legislative victories. They followed through on this plan. As Mitch McConnell explained proudly in 2010, “Our top political priority over the next two years should be to deny Barack Obama a second term.”

The Affordable Care Act itself was designed as something of a political compromise solution, containing elements of plans previously championed by Republicans. But Republicans in Congress closed ranks against the reform, eventually shutting down the government in protest of the law.

Senate Republicans’ attitude toward Obama’s judicial nominees has followed a similar pattern,even before the current Supreme Court showdown. As we noted last week, right-wing pressure groups and their allies in Congress, including Cruz and Sen. Mike Lee, were trying to shut down the federal judicial confirmation process in Obama’s final year before Scalia’s death.

If Grassley is really now refusing to even meet with Obama to discuss potential Supreme Court nominees, the Right should finally retire its talking point that it’s Obama who refuses to reach across the aisle.
