Schauer voted in 2012 GOP presidential primary

Michigan Democratic gubernatorial candidate Mark Schauer is acknowledging that he voted in the state's 2012 Republican presidential primary.

Schauer told reporters Wednesday he voted because there wasn't a Democratic presidential primary and he doesn't like to miss "any elections." He declined to say whom he voted for.

Eventual GOP presidential nominee Mitt Romney narrowly defeated ex-Pennsylvania U.S. Sen. Rick Santorum in Michigan.

State Republican spokesman Darren Littell says Schauer intentionally undermined the voting process and is "speaking out of both sides of his mouth."

The GOP secretly videotaped Schauer telling supporters earlier this year that they shouldn't cross over to vote in the 11th congressional district primary "especially when there are things at stake on our side of the ballot."
