Elected lawmakers in Kansas have cut income taxes, lowered the age for carrying a concealed gun and improved regulations of state election laws by overriding Gov. Laura Kelly’s vetoes of those measures. A series of votes Monday in the Legislature demonstrated that they can control policy if they hold together. The tax measure will provide $284 million in relief over three years. The gun legislation will allow 18-, 19-, and 20-year-olds to carry concealed firearms. The elections bill will better regulate how people collect absentee ballots from voters and deliver them to election officials.
