TOPEKA, Kan. (AP) _ Republican legislators in Kansas are tossing around plenty of proposals for raising new revenues to help close the state's budget shortfalls. They're not confining themselves to rethinking personal income tax cuts that represent GOP Governor Sam Brownback's legacy. But many lawmakers floating the ideas also aren't expressing much enthusiasm for them. Several Republican leaders said the GOP-dominated Legislature also must make significant spending cuts in addressing shortfalls totaling more than $710 million in the current and next budgets. The tax proposals from senators include delaying future promised cuts in personal income tax rates and accelerating the elimination of income tax deductions already being phased out as rates drop. Legislators also have mentioned eliminating exemptions to the state sales tax and increasing gasoline, liquor and tobacco taxes.
