TOPEKA — Kansas Republicans pressing to reform the Legislature’s annual budget-writing process want to displace governors from the lead role in proposing state spending changes, alter a Statehouse culture that embraced the three-day workweek, and make it difficult for lobbyists to slip special-interest earmarks into bills.House Speaker Dan Hawkins and Senate President Ty Masterson, the Republicans who formed an interim legislative committee to work on the budgeting overhaul, said the plan involved formation of a powerful permanent committee of a dozen or so legislators who would start work on a version of the state budget as much as three months before the legislative session began in January.
