People do it all the time. Some are just better at it than others. Shall we review the record?
In 2000, the GOP nominated an admitted alcoholic, who had probably also abused illegal substances earlier in life. His wife killed someone in a traffic accident when she was a teenager. His VP nominee had a record of multiple DUIs, and had had four heart attacks.
Yet each of these people had many positive qualities, and the GOP successfully presented them to the American people as positive roll models who you could be proud to vote for.
I'd say you are a lefty.
The term for someone who has not had a drink in over a decade is recovering alcoholic.
