Backers of a proposed casino and resort in southwest Virginia are ramping up efforts to boost support for the project before it goes to voters for a decision. Virginia lawmakers opened the door for the project earlier this year, and now voters in Bristol must approve it in a public referendum. While Election Day isn’t until Nov. 3, early voting starts later this month. A pro-casino referendum committee has sent mailers, placed signs, bought advertising and announced small businesses that support the project, the Bristol Herald Courier recently reported. If approved, a gaming license application could be submitted as soon as late 2020.
