Today’s conversation What? Who? Where? Why? How?
Today’s conversation What? Who? Where? Why? How?
What is “redistricting”? Draw (and re-draw) lines that determine which voters are represented by each legislative seat Federal State Local
Why re-draw district lines? Population moves, creating lopsided districts where some votes are worth more than others
Constitutional mandate to redraw lines Districts must have roughly equal population Baker v. Carr, 1962 “One person, one vote”
2000― 2001― 2010― 2011 ― 2020― 2021 ― And so… Census Day Redistricting Census Day Redistricting Census Day Redistricting
Key redistricting dates April 1, 2010― December 31, 2010― January 10, 2011― April 1, 2011― End of session 2011 ― or early 2012 Census Day Census count to President Apportionment to U.S. House Redistricting data to states Most redistricting complete

Who draws the lines In most states, the legislature has primary control State legislative districts: 37 states Congressional districts: 38 states (and 7 states with 1 Congressional district)
Other redistricting institutions AdvisoryPrimary control in the legislature Primary control outside legislature Politician Backup State legislative districts Congressional districts * *
2000 cycle judicial action State leg.Congress * Courts asked to step in3221 Court drew lines itself109 … and if that should fail * 7 states had only one congressional district in the 2000 cycle

“Where” starts with federal protections Equal population Race/ethnicity and the Voting Rights Act
Equal population Congress: as equal as possible State legislature: 10% spread, if there’s a good reason Baker v. Carr, 1962 “One person, one vote”
“Where” starts with federal protections Equal population Race/ethnicity and the Voting Rights Act
Minority representation Cracking Packing
The Voting Rights Act Do minorities represent most of the voters in a concentrated area? Do white voters vote for different candidates than minorities? Section 2
The Voting Rights Act Section 2 Do minorities represent most of the voters in a concentrated area? Do whites tend to vote for different candidates than minorities? Is the minority population otherwise protected given the “totality of the circumstances”? Do Not Dilute
Complying with the Voting Rights Act Latino/Hispanic African-American Chicago suburbs
The Voting Rights Act Section 5 “Preclearance” for certain jurisdictions Is the new map intended to dilute minority votes? Does the new map leave minority voters worse off?
Race and ethnicity beyond the VRA Voting Rights Act protects minorities who are more than half of the voters in an area With smaller groups of minorities, it is OK to consider race and ethnicity, among other factors Race and ethnicity just can’t “predominate” without a really good reason
Warning signs when race or ethnicity “predominates,” outside of a VRA district Legislative testimony with sole focus on race Population data much more detailed for race Shape explained by race, but not by “traditional districting factors” Race and ethnicity beyond the VRA

Communities of interest Kansas -- “Social, cultural, racial, ethnic, and economic interests common to the population of the area, which are probable subjects of legislation... should be considered. [S]ome communities of interest lend themselves more readily than others to being embodied in legislative districts...” Can and should be different in different parts of the state
Communities of interest Social interests Cultural interests Racial / ethnic interests Economic / trade interests Geographic interests Communication and transportation networks Media markets Urban and rural interests Occupations and lifestyles

Why does redistricting matter? If you care about representation, and you care about political power, then you care about redistricting should
~ 27 % of Congressional districts were drawn to be competitive ~ 9 %of Congressional races were competitive ~ 19 %of Congressional races had no major party opponent ~ 25 %of state House races were competitive * ~ 40 %of state House races had no major party opponent * Blunt measure #1: voter choice * 37 states measured Source:Gary C. Jacobson, Competition in U.S. Congressional Elections David Lublin & Michael McDonald, Is It Time to Draw the Line?
District Partisanship Incumbent Situation Election Outcome Candidate Type Money Raised National Mood Demographic Change Campaign Finance Term Limits Redistricting Source: Michael McDonald & John Samples, The Marketplace of Democracy 14 But redistricting is only part of the process
Blunt measure #2: shape
Is this a good district? You can’t know if a district is “good,” unless you know what it’s trying to achieve Is she a good singer?
And pretty shapes are not neutral Source:Michael McDonald, Midwest Mapping Project
Why does redistricting matter? Politicians choosing their voters Eliminating incumbents or challengers
Conflating public, partisan, personal interests Barack Obama’s house Barack Obama: strong challenge for Congress in district
Conflating public, partisan, personal interests Lorraine Koppell’s house Lorraine Koppell: strong challenge for state Senate in district
Conflating public, partisan, personal interests Hakeem Jeffries’s house Hakeem Jeffries: strong challenge for state Assembly in district
Why does redistricting matter? Politicians choosing their voters Eliminating incumbents or challengers Diluting minority votes Splitting up communities

How to make sure districts are drawn in the public interest?
Principles for effective redistricting 1.Meaningful transparency 2.Meaningful independence 3.Meaningful diversity 4.Meaningful guidance
Principles for effective redistricting 1.Meaningful transparency 2.Meaningful independence 3.Meaningful diversity 4.Meaningful guidance
Meaningful transparency Multiple opportunities for meaningful public input -Before drafts -After drafts Data and tools to facilitate response Some explanation from redistricting body
Principles for effective redistricting 1.Meaningful transparency 2.Meaningful independence 3.Meaningful diversity 4.Meaningful guidance
Meaningful independence One of the players shouldn’t also be the umpire This is not the same as taking politics out of redistricting Legislature can still have a role -Select those who draw the lines -Review lines afterward
Principles for effective redistricting 1.Meaningful transparency 2.Meaningful independence 3.Meaningful diversity 4.Meaningful guidance
Meaningful diversity Those who draw the lines should reflect the state Need redistricting body of sufficient size Need rules/incentives to choose diverse membership
Principles for effective redistricting 1.Meaningful transparency 2.Meaningful independence 3.Meaningful diversity 4.Meaningful guidance
Meaningful guidance Criteria that reflect basic goals Enough flexibility to accommodate local exceptions Communities of interest Statewide majority is legislative majority
Public Participation This round of redistricting will be different than the past. The public will have new tools that will enable them to be more active participants in the redistricting process. These tools may be used for local redistricting.
