INDIANAPOLIS (AP) — Indiana Senate Republicans want to make changes in the way legislative district maps are drawn to lessen political factors used in redistricting.

They plan to introduce a bill in the upcoming session that would require lawmakers who draw new maps in 2011 to use guidelines that would try to keep districts compact and avoid dividing communities, neighborhoods and precincts.

They also said Thursday they want to create a two-year study committee that could ultimately lead to a constitutional amendment establishing an independent commission to draw new House and Senate maps every 10 years.

Republicans have a large majority in the state Senate, but Democrats control the House.
