A Democratic-backed plan to change rules on congressional redistricting is setting up a nasty partisan fight in the final weeks of the legislative session, The Denver Post reports.

Introduced late last week, House Bill 1408, sponsored by House Majority Leader Paul Weissmann, D-Louisville, would eliminate a law Republicans passed in 2003 that dictates factors a court is to consider if the legislature fails to draw up a redistricting plan.

The bill is up for its first hearing in a House committee today. The session ends no later than May 12.
