In most presidential elections, Supreme Court nominations are a major issue for elites and a substantial concern for significant parts of the conservative movement. Other voters usually see the future makeup of the court as a side matter, or not essential to their decisions at all.
Justice Antonin Scalia's death on Saturday will change this.
The issue of conservative judicial activism had already begun to take hold among liberals because of a series of fiercely ideological and precedent-shattering 5-to-4 decisions.Don't miss outSign up for The PointCartoonDavies' latest cartoon: Nassau's got mailCommentSubmit your letter
You read that right: After decades during which conservatives complained about "liberal judicial activism," it is now conservatives who are unabashed in undermining progressive legislation enacted by the nation's elected branches. Scalia will be remembered fondly on the right as the brilliant exponent of the theory of "originalism" that provided a rationale -- or, in many cases, a rationalization -- for decisions that usually fit conservative ideological preferences.
In 2010, Citizens United rewrote decades of precedent on Congress' power to regulate how campaigns are financed, facilitating a flood of money into elections from a small number of very wealthy Americans. Three years later, Shelby County v. Holder ripped the heart out of the federal government's enforcement power in the Voting Rights Act. Last week, conservatives on the court halted the implementation of President Obama's Clean Power Plan, his central initiative on climate change.
This is merely a partial list. The court's conservatives have also regularly undercut the power of unions and the ability of citizens to wage legal battles against corporations.
Such decisions already had the potential of broadening the range of progressive constituencies invested in making the court a major election issue, including political reformers, African-Americans, environmentalists and organized labor.
But Scalia's death means that Obama or his successor -- if that successor is a Democrat -- could overturn the current conservative majority on the court, which could lead it to revisit many of the most troubling decisions of recent years.
And Republicans did themselves no favors in the coming argument by moving in a hard political direction even before most of the tributes to Scalia had been published -- and even before the president had actually picked someone: Senate Majority Leader Mitch McConnell proclaimed that no Obama nominee would be considered, period.
"The American people should have a voice in the selection of their next Supreme Court justice," McConnell said. "Therefore, this vacancy should not be filled until we have a new president."
Republicans claimed precedent for ignoring court appointees from presidents on their way out the door. During Saturday night's debate in South Carolina, Marco Rubio said that "it has been over 80 years since a lame-duck president has appointed a Supreme Court justice." Ted Cruz made a similar point.
Well. A Senate controlled by Democrats confirmed President Reagan's nomination of Anthony Kennedy on a 97-0 vote in February 1988, which happened to be an election year. By what definition was Reagan not a lame duck when he put Kennedy forward on Nov. 11, 1987?
Obama rejected the rejectionists. He said Saturday he would name a new justice and that there would be "plenty of time ... for the Senate to fulfill its responsibility to give that person a fair hearing and a timely vote."
My hunch is that Obama will try to put the Republicans' obstructionism in sharp relief by offering a nominee who has won support and praise from GOP senators in the past. Three potential candidates who fit these criteria and won immediate and widespread mention were Merrick Garland and Sri Srinivasan, both judges on the U.S. Court of Appeals for the District of Columbia, and Jane Kelly, a judge on the Eighth Circuit. (I should note that Garland is a dear friend of long standing.)
Whatever choice Obama makes, he will try to make it as hard as possible for Republican senators -- especially those struggling for re-election this year in blue or purple states -- to claim that he had picked an ideologue. Obama could also argue he had deferred to the Republicans' Senate majority by offering a candidate whom many of them had supported in the past.
An extended court fight would allow progressives, once and for all, to make clear it is their conservative foes now using judicial power most aggressively. The partisan outcome of this year's election just became far more important. This fall, Americans will not just be picking a new chief executive. They will be setting the course of the court of last resort for a generation.
