Five months out from Election Day, the structural indicators that most reliably predict midterm outcomes are pointing in the same direction. FGS Global's Alternative Futures team is tracking the month-over-month movement of six core election indicators. Since March, structural fundamentals have stabilized, modestly easing Republican seat exposure. Here’s where each indicator stands:
Iran: Opposition to military action stands at 57.4%. The recently signed Memorandum of Understanding (MOU) ending hostilities introduces a new variable – its durability, and its real-world impact on gas prices and inflation will determine whether the conflict remains an electoral liability or fades as a factor by November.
Presidential approval: Trump's net approval sits at -18.9% (38.9% approve, 57.8% disapprove) as of June 18. Historical trends at this level correlate with Republican House seat losses. The deterioration has stopped, but 45% remains the threshold that makes the House competitive for Republicans.
Generic congressional ballot: Democrats lead 48.0% to 41.7%, a +6.3% margin. Stable, but below where the 2018 Democratic wave stood at this point in the cycle.
Economy: Inflation hit 4.2% year-over-year in May – a three-month high. Consumer sentiment ticked up 9% in June's preliminary read but remains 19% below a year ago. Historically, negative economic perception favors the opposition party.
Prediction markets: Kalshi and Polymarket both favor Democrats to flip the House (77% and 81% respectively) – but Republican odds of retaining the Senate have strengthened (56-58% chance of a GOP hold), a reversal from spring when Democrats were briefly favored.
Competitive seats: Cook Political Report moved Alaska and Iowa to lean Republican, putting 9 Senate seats in play. House toss-up-or-lean seats edged from 36 to 35, with new Republican-drawn maps tightening Democrats' path to the majority.
