HARRISBURG, Pa. (AP) — Lack of interest has thwarted Pennsylvania’s latest casino expansion attempt. The Pennsylvania Gaming Control Board on Wednesday received no bidders for a casino license auction ordered by lawmakers as part of an aggressive gambling expansion launched by a cash-hungry state government. The auction was limited to owners of Pennsylvania’s full-size casinos. Minimum bids were set at $7.5 million and potential locations were limited to parts of northern and central Pennsylvania.
