State Rep. Shane Schoeller, a Republican candidate for secretary of state, is up with his third television ad, this time focusing on his support for requiring a government-issued photo ID in order to cast a ballot.

In the ad, Schoeller says photo identification is needed to "drive a car, get on a plane, get a hotel room, even rent a movie."

"So why don't we require voters to have an ID?" he asks in the ad.

Schoeller sponsored a voter ID law this year in the Missouri House, but it did not clear the Senate.

In 2006, Republican lawmakers passed a voter ID bill that was later struck down by the Missouri Supreme Court. The court said the law amounted to a “heavy and substantial burden on Missourians’ free exercise of the right of suffrage.”

In response to the court’s ruling, lawmakers passed a proposed constitutional amendment allowing a photo ID requirement to vote. They also passed a companion bill that laid out the guidelines for implementing a photo ID law, should voters approve it.

Gov. Jay Nixon vetoed the implementation bill, and a Cole County Judge struck the constitutional amendment off November's ballot.

Schoeller's ad ends by noting he won the endorsement of former governor and U.S. Attorney General John Ashcroft. He faces off with a pair of Republican Senators -- Scott Rupp of Wentzville and Bill Stouffer of Napton -- in the Aug. 7 Republican primary.
