A poll taken by the Florida Chamber of Commerce indicates only four of the 13 state constitutional amendments on the November ballot have enough voter support to pass. They are:  Amendment 1, which would expand the homestead property-tax exemption – Amendment 3, which would require voter approval of gambling expansions in the state, including allowing casinos – Amendment 7, which would require the payment of death benefits when law enforcement officers, paramedics, correctional officers and other “first responders” are killed while performing their official duties – and Amendment 8, which would impose an eight-year term limit on school board members and require teaching civic literacy in public schools. The other nine proposed Amendments fell short of the 60 percent approval requirement in the poll.
