With the passage of gambling expansion in Maryland and a new casino on the horizon, one county’s loss is another’s gain.

West Virginia’s Jefferson County, home of the Hollywood Casino at Charles Town Races, is facing a drop in its millions of dollars of yearly gaming revenue as more Maryland gamblers are likely to stay in state thanks to Question 7. The measure, which voters approved 52 percent to 48 percent, allows for a new casino in Prince George’s County along with table games and 24-hour operation at existing casinos statewide.
