Texas Redistricting Evaluation of Plan C141
-
by Stephen Ansolabehere and Maxwell Palmer
Last week, the Texas State Senate passed redistricting plan C14 1. The plan adds four new seats. which were allocated to Texas based
on the 2010 census. This memo presents results using standard methods for assessing the likely partisan consequences of plans. We
map past election results into the current districts in order to calculate what percent of seats are majority Republican and what percent
of seats are majority Democrat. We further considcr the possibility of uniform shifts in the statewide vote, either in the direction of
Democrats or Republicans, to assess the likely affects of the plan on the division of seats in future elections. Of particular interest is
the projected division of seats in the hypothetical case when the statewide vote is divided evenly between the parties. This value is
called the “partisan bias” of the districting plan (see Browning and King 1987).
Based on the 2008 presidential election results, twenty-two of the twenty-three current Republican members of Congress will be in
districts in w’hich Republicans arc expected to receive 55 percent of the vote or more, and eight of the nine current Democratic
members of Congress will be in districts in which Democrats are expected to receive 55 percent of the vote or more. Democrat Lloyd
ih
Doggett’s 25
district will go from 60% Democratic to 55% Republican. Of the four new districts, two are districts where we expect
Republicans to receive 55% or the vote or more, and two are districts where we expect Democrats to receive 55% of the vote or more.
Consequently, if Doggett is defeated due to the shift of his district from heavily Democratic to Republican, the Republicans will
increase their congressional delegation from twenty-three to twenty six seats, and the Democrats from nine to ten seats.Jjl
Analysis of the plan also allows us to project the likely division of the legislature for different (hypothetical) divisions of the vote
statewide. We plot these results on a seats-votes curve. where each point on the plot represents the percentage of seats that would be
won by the Democrats for the given vote share. [1

This curve reveals two important features of this plan. First, the plan has a partisan bias of 14—1 7%.
Rather than winning 50% of the seats in the hypothetical case where the Democrats win 50% of the vote,
the Democrats would win only 43—46% of the seats. To win 50% of the seats, the Democrats would need
to win roughly 52—53% of the vote.

Second, the number of seats won by each party is constant for any Democratic share of the vote between
thirty—seven and forty—eight percent. This range includes the recent statewide performance of most
Democratic candidates over the last ten years, which has averaged 42%. This flat portion of the seats—
votes curve indicates extremely low competitiveness in almost all of the congressional districts under this
plan. Thus, the plan is not responsive to small changes in the vote share of either party in the range of
vote shares that we expect in the next elections. All of the changes in the makeup of Texas’
congressional delegation are likely to be the result of the partisan decisions in the redistricting process,
rather than from competitive congressional elections.

Hello
and redistricting
...
—
I hope all is well with you and Aynsley in Austin. I had dinner recently with Kevin Robnett and he mentioned that you guys
were doing really well.
I wanted to touch base with you regarding redistricting, as I am handling things for Congresswoman Granger here in
Texas. If possible, I would like to chat for just a bit over the phone about how things are looking on your end in order to
keep my boss informed as things progress. I know that session starts next week and your life will be full speed through
May. My contact information is below but feel free to email if it is easier to set up a time.
Many thanks,
Mattie

Hey man, Ellie an I came to town for the inauguration today and my boss just called and asked
me to go on a goodwill mission to the legislative council office tomorrow and talk to the
guy(s) in charge of mapdrawing, just to introduce myself.
Was hoping you might be able to point me in the right direction as far as who the key people
are. Thanks so much, man.

Tony,
I know we don’t know each other, but I am a person of my word. I told you that when we knew a schedule I would let you
know. A schedule has not been agreed to at this point and discussions are ongoing between the House and the Senate.
When a schedule is concrete, I will be happy to let all members of the Congressional delegation who have inquired know
of Chairman Solomons’ intent. I sympathize and understand the need to make travel arrangements and will try to give you
as much advanced notice as is possible.
On a note about the hearing, if the Congressional members wish to have theirwishes heard by the Texas Legislative
members of the Redistricting Committee, it might be wise for them to deliver their testimony in person.
Cordially,
