Ex-girlfriend says political consultant who worked on Gov. Walker campaign damaged her vision

LAS VEGAS — The ex-girlfriend of a former Nevada political consultant facing allegations of domestic violence says she has permanent vision damage after he struck her in the eye.

Former GOP consultant Benjamin Sparks is due in a Las Vegas courtroom Tuesday to answer to a misdemeanor battery charge after prosecutors say he grabbed or pushed the woman in March.

Sparks does not yet have a listed attorney and did not answer a phone call seeking comment Monday.

The Las Vegas Review-Journal reports Sparks' ex-girlfriend, who is being represented by celebrity attorney Gloria Allred, filed a report Friday with police alleging Sparks hit her in the eye and left her with a torn retina in March.

Sparks had worked on Republican campaigns for Nevada Rep. Crescent Hardy, Wisconsin Gov. Scott Walker, New Mexico congressional candidate Yvette Herrell and Mitt Romney's 2012 presidential campaign.
