The choice of Merrick Garland for the U.S. Supreme Court leaves President Barack Obama’s allies selling the nomination process more than the man himself as they try to pressure Republican senators.

That could mean Obama will face an enthusiasm gap when it comes to trying to use Garland’s nomination to motivate the party’s base to turn out in November. 

By selecting a 63-year-old white man with a record moderate enough to win the praise of Utah Republican Senator Orrin Hatch, Obama spurned the wishes of some of his most fervent backers, who wanted him to name a minority who would make history, a younger outspoken progressive, or preferably both.

And while a number of liberal groups are launching campaigns to pressure Republicans, they aren’t rallying around Garland so much as they are rallying against Republicans for obstructing the president. 

"This is not really a campaign for a person," said Murshed Zaheed, the political director of CREDO Action, one of dozens of liberal groups demanding that Senate Republicans consider Garland. "This is a campaign for a process, a campaign for the Constitution and a campaign against a band of extreme right wing radical Republicans who have taken the Senate hostage."

Since Garland’s nomination on March 16, there have been few signs that his reputation as a moderate and his decades of experience on the federal bench were doing much to sway Republicans to drop their blockade and grant him a hearing and a vote on the Senate floor.

Even Hatch, who had urged Obama to nominate Garland for previous court openings and predicted he could get confirmed easily, said the Senate should not act until after the election.

Long Slog

Garland’s nomination almost immediately turned into a stalemate that could last for months. 

For Republican senators, their blockade isn’t about Garland, or even really their newly invented talking point that the public should get a chance to weigh in in November. It’s about the balance of power at the court. They don’t want to let it swing from a majority of Republican-nominated justices to a majority of Democratic-nominated justices for the first time in decades if they can do anything to stop it.

Wisconsin Senator Ron Johnson said he’d be willing to meet with Garland, but the session would be pointless.

"I’ll meet with the guy, but trust me, we’re not going to let the Supreme Court flip and this nominee obviously would flip the court, particularly on an issue pretty important to Wisconsin -- the right to keep and bear arms," said Johnson, who is facing a difficult re-election campaign.

Indeed, early opposition from the National Rifle Association is just one of many reasons why Garland is almost certain to languish without a hearing, at least until November. Anti-abortion groups and other organizations critical to Republicans would also roast the party’s senators if they caved.

"I can’t imagine that a Republican majority in the United States Senate would want to confirm in a lame-duck session a nominee opposed by the National Rifle Association, the National Federation of Independent Business that represents small businesses that have never taken a position on the Supreme Court appointment before," Majority Leader Mitch McConnell of Kentucky said on "Fox News Sunday."

Pressure Campaign

Senate Minority Leader Harry Reid of Nevada said Democrats will keep pounding the table for a hearing and will also be mounting a broad public-relations offensive to pressure Republicans.

“You’re seeing historic grassroots support around a Supreme Court nominee, not just because that’s what is necessary to combat the Senate Republicans’ unprecedented obstruction, but because Chief Judge Garland is one of the most qualified judges we’ve seen in a generation," said Amy Brundage, a former deputy White House communications director for Obama who is helping coordinate a broad coalition of groups to confirm Garland.

The push includes events to be held by liberal groups such as MoveOn.org aimed at pressuring Republicans back in their states.

But liberal groups, while united in opposition to the blockade, aren’t all that excited by Garland, who doesn’t have an activist liberal record and wouldn’t diversify the court.

"It’s deeply disappointing that President Obama failed to use this opportunity to add the voice of another progressive woman of color to the Supreme Court," Charles Chamberlain, executive director for Democracy for America, said last week.

Garland, meanwhile, won’t be talking to the press, and, if Republicans hold firm, won’t be getting a chance to answer questions in a hearing either. That makes him essentially a mute prop in what will be dozens of courtesy calls with mostly Democratic senators.

One senior Democratic aide acknowledged liberal concerns about diversity and the lack of excitement from Garland himself, but said that Republicans’ refusal to even hold a hearing on the nominee would represent a slap in the face to the president and his supporters.

‘Best Person’

The White House has fended off questions about disappointment among liberals over Obama’s decision not to pick a black justice, another minority or a younger pick more likely to stay on the court for decades.

Obama had considered naming several minority judges, Paul Watford, an African American judge on the 9th U.S. Circuit Court of Appeals, and Sri Srinivasan, a judge on the U.S. court of Appeals for the D.C. Circuit who would have been the first Asian-American and the first Hindu on the high court.

The pick also got a cool reception from Democratic presidential candidate Bernie Sanders, who said on MSNBC last week he would ask Obama to withdraw the nomination if elected president so he could nominate a more liberal judge.

White House Press Secretary Josh Earnest touted Obama’s track record of appointing African Americans and other minorities for lower court picks, but said Obama wants his legacy to choose "the best person for the job."

The White House has started emphasizing nonjudicial aspects of Garland’s life, like his nearly 20 years of tutoring at a Washington, D.C., school, in a video featuring a testimonial from a black second-grade teacher.

The calculation on the part of the White House -- and among senators who had urged a moderate pick -- has been to make it as difficult as possible for Republicans to block the pick, thereby showing them as obstructionists. And Garland fits that bill.

Trump Effect

The Republican blockade could become fodder to Democrats to motivate their base to turn out in November, but Democrats are counting more on Republican frontrunner Donald Trump to do that, the aide said.

Democrats’ campaign arms are also attacking vulnerable Republicans, charging them with doing Trump’s bidding in blocking a nominee.

Democrats tried last week to seize on comments from several Republicans that they would at least meet with Garland to suggest the Republican blockade was already cracking. But almost all Republicans continued to back the no-hearings, no-votes course set by McConnell and Judiciary Committee Chairman Chuck Grassley of Iowa after Justice Antonin Scalia’s death last month.

Those meetings could lead to some uncomfortable photo ops in the coming weeks, with Garland expected to sit down with Grassley, Johnson, Rob Portman of Ohio and Kelly Ayotte of New Hampshire, all of whom have made clear they back the blockade and face re-election in November against Democratic challengers in states won twice by Obama.

"You meet with him and then hopefully that maybe changes your mind and you think at least we should have a hearing," said Senator Amy Klobuchar of Minnesota, a Democratic member of the Judiciary Committee. "But I think what’s really going to change their mind is their own constituents, people asking them why they can’t have a hearing, why they can’t do their job."

Dug In

But there’s no evidence that will work, given that most voters in polls have already said the Senate should act and Republican leaders haven’t budged.

Senators Mark Kirk of Illinois, who also faces the voters in November, and Susan Collins of Maine, reiterated their earlier positions that the Senate should consider the nomination on the merits.

But another targeted Republican, Pat Toomey of Pennsylvania, tweeted out a hard-line stand against confirming any Obama nominee.

Garland’s best chance for confirmation would come after a Democratic victory in the presidential election, with a few Republicans -- Hatch and Jeff Flake of Arizona -- initially sounding open to the idea, although Hatch later walked back his remarks to reporters.

"I would choose a less liberal nominee, and this nominee is certainly a less liberal nominee than we would get, I’m quite certain, with Hillary Clinton nominating," Flake said.

McConnell and the second-ranking Republican in the Senate, John Cornyn of Texas, have tried to squelch such talk. After all, if the Senate might be willing to consider a nominee in the lame duck session, why not at least vet the nominee and hold hearings in advance? Those are questions they don’t want to have to answer.
