Remember the storm that arose on the political left after the U.S. Supreme Court upheld the constitutionality of Indiana's voter ID law last April? According to the left, voter ID was a dastardly Republican plot to prevent Democrats from winning elections by suppressing the votes of minorities, particularly African-Americans.

Since the election of Barack Obama, we haven't heard a word about such claims. On Jan. 14, the federal appeals court in Atlanta upheld Georgia's voter ID law.

The reasons for the silence about alleged voter suppression is plain. In the first place, numerous academic studies show that voter ID had no effect on the turnout of voters in prior elections. The plaintiffs in every unsuccessful lawsuit filed against such state requirements could not produce a single individual who didn't either already have an ID or couldn't easily get one.

Second are the figures emerging from the November election. If what liberals claimed was true, Democratic voters in states with strict photo ID requirements would presumably have had a much more difficult time voting, and their turnout dampened in comparison to other states. Well, that myth can finally be laid to rest.

The two states with the strictest voter ID requirements are Indiana and Georgia. Both require a government-issued photo ID. According to figures released by Prof. Michael McDonald of George Mason University, the overall national turnout of eligible voters was 61.6%, the highest turnout since the 1964 election.

The Joint Center for Political and Economic Studies (JCPES) found that black turnout in the 2008 election was at a historic high, having increased substantially from 2004. The total share of black voters in the national vote increased from 11% to 13% according to exit polls, with 95% of blacks voting for Mr. Obama.

So what happened in Georgia where the ACLU, the NAACP and other such groups claimed the state's photo ID law was intended to depress black turnout? According to figures released by Curtis Gans at American University, Georgia had the largest turnout in its history, with nearly four million voters. The Republican turnout was up only 0.22 percentage points; the Democratic turnout was up an astonishing 6.1 percentage points, rising from 22.66% of the eligible voting population to 28.74% of the eligible population.

The overall turnout in Georgia increased 6.7 percentage points from the 2004 election -- the second highest increase in turnout of any state in the country. According to the JCPES, the black share of the statewide vote increased in Georgia from 25% in the 2004 election, when the photo ID law was not in effect, to 30% in the 2008 election, when the photo ID law was in effect.

By contrast, the Democratic turnout in the neighboring state of Mississippi -- which has no voter ID requirement but also has a large black population similar to Georgia's -- increased by only 2.35 percentage points.

In Indiana, which the Supreme Court said had the strictest voter ID law in the country, the turnout of Democratic voters in the November election increased by 8.32 percentage points. That was the largest increase in Democratic turnout of any state in the country. The increase in overall turnout in Indiana was the fifth highest in the country, but only because the turnout of Republican voters actually went down 3.57 percentage points. The nearby state of Illinois (no photo ID requirement) had an increase in Democratic turnout of only 4.4 percentage points -- nearly half Indiana's increase.

Of course, the decline in Republican turnout and huge increase in Democratic turnout in Indiana matched what happened elsewhere, and explains why Mr. Obama won. Republican turnout nationwide declined 1.3 percentage points from the 2004 election, while Democratic turnout increased 2.6 percentage points.

The JCPES predicts that when the final turnout numbers are in for the 2008 election, black turnout will probably reach a historic high of almost 67% and likely surpass white turnout for the first time. All at a time when about half of the states have passed various forms of voter ID requirements, including two states with strict photo ID laws.

The claim that Republican legislatures in Georgia and Indiana passed voter ID to depress Democratic turnout is demonstrably false. But even if it were true, they obviously failed miserably to achieve that objective given the huge increases in Democratic and minority turnout in both states.

I guess liberals will now claim that their historic increases in turnout would have been even higher if not for voter ID laws. But that would be an absurd argument, given the states' performance in comparison to other states without voter ID laws.

With every election that has occurred since states have begun to implement voter ID, the evidence is overwhelming that it does not depress the turnout of voters. Indeed, it may actually increase the public's confidence that their votes will count.

That won't stop the ACLU or the League of Women Voters from filing more frivolous lawsuits against such state laws and continuing to waste taxpayer money. But ultimately they will lose, and our ability to protect the security and integrity of our elections will be preserved.
