Republicans who hold a House majority predict a committee will approve a proposed constitutional limit on state spending.
Urbandale Rep. Scott Raecker says the House Appropriations Committee should approve the measure Wednesday, then the full House will later OK the proposal.
Republicans acknowledge the measure likely won't be approved in the Senate, where Democrats hold a majority.
The proposal would add a requirement to the Iowa Constitution that the state spend no more than 99 percent of what it collects in taxes.
It also would require a 60 percent legislative vote before the state could raise taxes, and a two-thirds vote to issue bonds. Such legislation now can be approved with a simple majority.
Voters would have to approve the measure before it could be written into the state constitution.
