The ’26 Redistricting Fight Puts Political Data in the Spotlight

Texas Republicans’ decision to redraw congressional maps ahead of the 2026 midterms has prompted other states, including California and Missouri, to consider similar moves. These changes will alter the boundaries of who campaigns can reach and how resources are allocated. 

In this environment, access to accurate, up-to-date data becomes critical. Reliable voter and demographic information allow campaigns and organizations to adjust their outreach, optimize paid media, and refine fundraising strategies based on the new district lines. Here’s what to look for in a data vendor to help with your voter outreach, paid media and fundraising:  

Historical Leadership 
Not every data vendor has experience tracking Americans’ migration, but having that historical perspective will be key to understanding the shifting landscape. 

We have a 40-year history tracking U.S. migration from state to state, county to county all the way down to the Census block. Our data comes from several sources, including our internal monthly consumer updates that capture changes by address, name, phone and email. This information is supplemented with data from Cicero , public deed records, utilities, credit sources, magazine subscriptions, and other trusted partners.

Our reports have been so popular that Bloomberg recently relied on Melissa when telling various American migration stories.  

Now, voters may find themselves having migrated to a new congressional district without packing a single box. Knowing who’s new to a district — whether a voter or a donor — will be key for campaigns this year and next.
