Geoffrey Skelley, Chris Cillizza, Maddisen Murrell · Decision Desk HQ

DDHQ friend Chris Cillizza, who runs So What on Substack, was nice enough to have two members of the DDHQ team on a Substack Live conversation about our 2026 election forecast. Chris was joined by Chief Elections Analyst Geoffrey Skelley and Data Science Fellow Maddisen Murrell to talk about the big picture and some specific U.S. Senate and U.S. House races. We’ll be doing this regularly every couple of weeks from now and until the election, so be on the lookout for more updates!
