AP analysis: Partisan redistricting limited GOP losses in 2018 midterms

With two major cases over partisan redistricting coming before the Supreme Court, how could the AP’s coverage stand out?

Missouri-based reporter David Lieb of the state government team provided the answer, taking the results of last year’s midterm election and applying a formula called the “efficiency gap” to measure the potential effects of highly partisan map-making on races for the U.S. House and state legislatures. The efficiency gap, developed at the nonpartisan Public Policy Institute of California and The University of Chicago, measures a party’s advantage on a statewide basis.

His finding: Democrats could have done even better last November had it not been for boundaries created by Republicans during the last round of redistricting – otherwise known as “gerrymandering.” His analysis showed that Republicans won about 16 more U.S. House seats – and held on to as many as seven state legislative chambers – than would have been expected based on their share of the vote.

Lieb and Data Team editor Meghan Hoyer previewed the state-by-state findings for customers and other AP reporters so the data could be used for localizations. The resulting package landed the week before the Supreme Court arguments, and the play was spectacular, both online and print.

The package was complemented by video and photos from national enterprise reporter Allen Breed, based in Raleigh, who traveled to a historically black college in North Carolina, where Republicans had split the campus between two districts, diluting the votes of the left-leaning student body.

Breed’s full-length video ran with the spot stories surrounding the Supreme Court arguments and parts of it were folded into a video graphic produced by New York deputy director for digital graphics Darrell Allen and Minneapolis-based video graphics newsperson Heidi Morrow. It became a key part of the extensive social promotion plan created by Alina Hartounian, the Phoenix-based multimedia coordinator for the beat teams.

For producing a distinctive multimedia package that made the AP stand out on one of the most important and competitive political topics of the day, Lieb, Hoyer, Breed, Allen, Morrow and Hartounian win this week’s Best of the States.

AP analysis: How gerrymandering benefited GOP in 2016

How is it that Republicans and Democrats can split the vote about equally in races for Congress and state legislatures, yet the GOP wins significant majorities in the House of Representatives and in statehouses across the country? Partisan gerrymandering, which manipulates legislative districts for one party’s benefit, has been suspected, but there has been no way to actually quantify it – until now.

An Associated Press team of David Lieb, Meghan Hoyer and Maureen Linke, applying a new statistical method that calculates partisan advantage, analyzed U.S. House and state legislative races across the country last year and found that redistricting controlled by Republicans had given their party a distinct advantage and one that will be hard for Democrats to overcome in upcoming election cycles.

Their multi-format report – including easy-to-grasp interactives and a trove of localized data – is the Beat of the Week.
