Leading Expert in Redistricting “Grofman,” Suggests a Path to Proving Partisan Gerrymandering

Bernard Grofman, author, professor at the University of California at Irvine, and an expert witness in a multitude of redistricting cases, published this article in the Washington Post today.  In it Grofman offers a way for courts to assess the level of partisan gerrymandering on a district-by-district basis when the challenge is based on the 14th amendment.  His assessment is timely, given the Supreme Court's recent decision in Gill v. Whitford, which rejected challenges to a map as a whole.  See our discussion of that here.  Grofman points to the court's line of racial gerrymandering cases as a guide and…

The FiveThirtyEight Blog Releases the Atlas of Redistricting. The Maps are Impressive but Unusable

  This week, the sports and politics polling blog FiveThirtyEight released its Atlas of Redistricting.  It takes a comprehensive look at the mapping possibilities for every congressional district in the nation, and is part of the site’s Gerrymandering Project, which seeks to uncover in their words, “[what] is greatly misunderstood . . .” about redistricting and whether “gerrymandering can (or should be) killed.” The maps are impressive.  They produce congressional maps for seven common, but vastly different redistricting goals.  The result is that you get to see what your (or any) state’s congressional map would like if it were drawn…

The Efficiency Gap Visualized Through the Decades

The Efficiency Gap Visualized Through the Decades

The hottest thing in redistricting - if there is such a thing - is undoubtedly the emergence of "Efficiency Gap" analysis, and whether this measurement of how gerrymandered a map is, will receive the imprimatur of the U.S. Supreme Court.  While we wait, The Campaign Legal Center has released this report looking back through the decades to measure the efficiency gap in state legislative and congressional maps.  Their point is that partisan gerrymandering has never been more rampant and excessive than right now, but the charts show other interesting patterns as well.  Read the Report here.

Texas Federal Court Imposes Preclearance on City of Pasadena

Pasadena, Texas - The United States District Court for the Southern District of Texas in this ruling invalidated the city's move from an eight-member district redistricting map to a mixed map of six single member districts and two at-large seats for electing its city council.  The court's finding of minority vote dilution (of Hispanic voters) under section 2 of the Voting Rights Act includes an order to subject the city to preclearance requirements, which would mean election officials must clear any future redistricting changes to the Justice Department for approval.  Read the initial case filing by plaintiffs here. There were several…

Federal District Court Finds Partisan Gerrymander in Wisconsin Assembly Map

Wisconsin -  A three-judge federal district court in Wisconsin has invalidated the Republican-drawn state assembly district map enacted in August 2011 as an unconstitutional partisan gerrymander.  If the ruling stands - and that's a very big "IF," this case will be the first successful approach to creating a workable standard for courts to use in determining whether a partisan gerrymander rises to the level of impermissible gerrymandering under the first amendment and equal protection clause of the U.S. Constitution.  Read more in the New York Times ,  Salon.com, Milwaukee Journal Sentinel, Washington Post, Wall Street Journal, and Rick Hasen's Electionlawblog.        Read the District Court…
