Oregon Republicans have filed a lawsuit against the new congressional districts that were approved by the special session of the legislature last month.  Former Oregon Secretary of State Bev Clarno is one of three Republicans behind the lawsuit.  They accuse Democrats of gerrymandering.  The lawsuit says the boundaries of the districts make it likely that Democrats will win five of the six seats in the House.  Oregon got a sixth congressional district, because the U.S. Census showed enough population growth in the state.
