New voter identification laws in Texas—passed by the state Legislature in 2011—will be enforced in the November 2013 election. The laws are being enforced by Attorney General Greg Abbott on the heels of a June 25 Supreme Court decision striking down a key part of the Voting Rights Act.

Voters who do not have a valid form of ID can apply for an election identification certificate for no cost at any driver's license office, said Hector de Leon, director of communications with the Harris County Clerk's office. The EIC is valid for six years, but any EIC issued to a voter older than 70 has no expiration date.

"There is no need to apply for the EIC if you already have one of the other six acceptable forms of ID," De Leon said.

The name on a voter's identification must match the name on the county's official list of registered voters, De Leon said.

He encourages voters to check how their name appears on the voter registration certificate by going online to the tax-assessor collector's website. Voters who are casting their ballot by mail do not need photo identification.

De Leon said it is difficult to gauge how many voters in Harris County will be affected by the law because they do not have the required identification.

"We're trying to educate people that they need to have one of the approved photo IDs," he said. "Voters make voting easier for themselves if they are prepared."

The U.S. Department of Justice filed a lawsuit challenging the constitutionality of Texas' voter identification laws, but the laws are still likely to be enforced in November elections.

Whether they will be in effect for future elections remains to be seen.

Representatives in the Houston area—including U.S. Rep. Sheila Jackson Lee and state representatives Jessica Farrar, Rodney Ellis and Garnet Coleman—have all spoken out against the laws, claiming they disenfranchise minority, elderly and economically disadvantaged voters. City officials in Austin passed a resolution Aug. 29 to look into participating in lawsuits filed against the voter laws.

De Leon said Harris County plans on complying with state law.

"As election administrators, we have to abide by and implement the law, and voters will have to abide by the laws as well," de Leon said. "We expect a smooth election like always."
