Kentucky Governor Steve Beshear will introduce a constitutional amendment on expanded gaming during the 2012 General Assembly.The governor told reporters an amendment is a better option than changing state law through the legislature, which convenes in January. Beshear made gaming a centerpiece of his 2007 gubernatorial campaign and his administration has lobbied for it as a means to help the horse industry and fill shortfalls in the state budget. However, the measure has continually failed to pass the Republican-controlled state Senate.It is expected Beshear will discuss the proposal during his inaugural address later today.
