LINCOLN, Neb. (AP) — A group that has helped thwart repeated attempts to expand gambling in Nebraska is gearing up again to fight a ballot campaign that would allow casinos at licensed horse racing tracks.

Gambling with the Good Life will campaign against the casino ballot measure and is looking for possible legal challenges similar to one last year, which knocked a historic horse racing proposal off the 2014 ballot. The group also plans to follow and videotape ballot petition circulators to see if any violate state rules.

The petition group, Keep the Money in Nebraska, began collecting signatures in October and has raised nearly $255,000.

Former state Sen. Scott Lautenbaugh, a group spokesman, says casinos would provide a new revenue source for state and local governments.
