Good point

Democrats Get a Gift From the Roberts Court 

By ROSS DOUTHAT 

... First, Republicans faced an unexpected (though in hindsight, predictable) undertow of their own, as many conservative-leaning, working-class white voters looked at what Mitt Romney had to offer and simply stayed home.

Second, instead of declining as expected after the history-making election of 2008, African-American turnout may have actually risen again in 2012. When the Census Bureau released its turnout analysis last month, it showed blacks voting at higher rates than whites for the first time in the history of the survey. 

If you believe Chief Justice John Roberts Jr.’s more overheated liberal critics, last week’s Supreme Court decision invalidating a portion of the Voting Rights Act is designed to make sure African-American turnout never hits these highs again. ...

If so, though, the Roberts Court may have actually handed the Democratic Party a political gift. 

How so? Well, to begin with, voter identification laws do not belong to the same moral or legal universe as Jim Crow. Their public purpose, as a curb to fraud, is potentially legitimate rather than nakedly discriminatory, and their effects are relatively limited. As Roberts’s majority opinion noted, the voter registration gap between whites and blacks in George Wallace’s segregationist Alabama was 50 percentage points. When my colleague Nate Silver looked at studies assessing the impact of voter ID laws, he estimated that they tend to reduce turnout by around 2 percent — and that reduction crosses racial lines, rather than affecting African-Americans exclusively. 

A 2 percent dip is still enough to influence a close election. But voter ID laws don’t take effect in a vacuum: as they’re debated, passed and contested in court, they shape voter preferences and influence voter enthusiasm in ways that might well outstrip their direct influence on turnout. They inspire registration drives and education efforts; they help activists fund-raise and organize; they raise the specter of past injustices; they reinforce a narrative that their architects are indifferent or hostile to minorities. 

This, I suspect, is part of the story of why African-American turnout didn’t fall off as expected between 2008 and 2012. By trying to restrict the franchise on the margins, Republican state legislators handed Democrats a powerful tool for mobilization and persuasion, and motivated voters who might otherwise have lost some of their enthusiasm after the euphoria of “Yes We Can” gave way to the reality of a stagnant, high-unemployment economy. 

So a lengthy battle over voting rules and voting rights seems almost precision-designed to help the Obama-era Democratic majority endure once President Obama has left the Oval Office.

Good point, if I say so myself.
