She has supported increased enforcement to deal with drunk driving.
She was recently arrested and charged with DUI (image is her mugshot at arrest).
Does this make her a hypocrite?
No.
She didn't say, "I will never DUI" or "no one should DUI".
On the other hand she may be a bad person as subsequent to the arrest she claimed she was taking prescription cough medicine and mistakenly had a beer with it. This seems suspicious and the police have said that she didn't mention the cough syrup at the arrest but that they could smell alcohol from 3 feet away.
