Districts drawn to elect minorities may cost Democrats control of House

McClatchy reports:

Republicans realized in the early 1990s that packing districts with reliably Democratic minorities improved Republican chances in next-door districts, and Democrats who wanted the majority-minority districts would go along. The strategy helped Republicans win control of the House in 1994 for the first time in 40 years, and the party has controlled the chamber for all but four of the last 20 years.

If Democrats are looking for the guilty : they should look into the mirror. Many in their base want districts that vote 90% one way.
