Pennsylvania state representatives are moving closer to a vote that would let the public decide whether to trim about a quarter of their own members.
The state House on Monday turned down a series of proposed changes to the constitutional amendment.
Amendments at this stage could prevent the constitutional referendum from being put before the state's voters this year.
A final vote in the House and passage by the Senate are still required.
The referendum would cut the size of the state House of Representatives from 203 to 151 members.
