Susanna Gibson, who is running to represent the 57th District in the Old Dominion’s House of Delegates, trails Republican David Owen by 49.5% to 38.9%, a Cygnal poll exclusively obtained by The Post shows.

Owen, a businessman, held a 4% lead among those voters when Cygnal conducted a previous survey of the race in August — before the Washington Post broke the news of Gibson’s online sex shows.

Since then, Gibson’s unfavorability rating has increased from 12.5% to 45.2% among likely district voters. Meanwhile, her favorability rating has declined from 28.1% to 27.3% between August and September….

The Cygnal poll showed 65% of likely general election voters in Gibson’s district don’t believe a “candidate for public office who posts publicly available videos online should be allowed to claim they should have privacy.”

[No kidding. If Gibson had just owned it and shrugged it off, would she have done better? It’s tough to say with a situation this extreme, but at least she would have avoided looking like a whiny hypocrite. Clearly that approach didn’t work. I’d bet that Democrats work extra hard to replace her on the ballot … if they can. — Ed]
