From Kentucky Public Radio's Tony McVeighA group opposed to expanded gambling is threatening to sue if video slots at Kentucky horse tracks are approved without a constitutional amendment.Governor Beshear is considering calling a special session to address looming state budget deficits, and horse industry officials are hoping expanded gaming will be on the call.But Kent Ostrander of The Family Foundation says if lawmakers approve video slots at horse tracks without first putting a constitutional amendment on expanded gaming before the people, the foundation will sue.“The Family Foundation has always been against the substance of any law that would expand gambling because we do not believe that government should take upon itself to encourage its people to lose in order that it might gain," he says.Ostrander says the foundation is capable of raising the funds necessary for a protracted legal battle and “we will win.”Governor Beshear’s office says the governor has made no decision yet on a special session or what may be on the call if there is one.
