Record $15B Midterm Spending Fuels Senate Battle as Early Voting Starts
More than $15 billion has been raised for the midterms, making them potentially the most expensive on record. Early voting is underway in key states like Texas and Minnesota, with Trump campaigning in deep-red areas amid GOP challenges and Democrats holding edges in some House forecasts.

Republicans enjoy a large Senate advertising lead driven by outside money, yet the House picture is far closer and early voting has already begun in pivotal states. The outcome hinges on whether that Senate spending edge can overcome narrower structural advantages and shifting voter sentiment in the final two weeks.
What outlets missed
The three articles omit any aggregate national fundraising total beyond the $15 billion headline figure and provide no state-by-state breakdown of early-vote access rules. They contain no data on how many House candidates have already suspended advertising entirely. No outlet reports the number of undecided voters in the seven Senate toss-ups or the share of spending still unreserved for the final fortnight.
Voters in key states begin casting ballots with more than $15 billion raised for the 2026 midterms, the largest sum recorded for a congressional election cycle. Control of the Senate remains the clearest point of contention, while the House majority appears more settled in Democratic forecasts.
Republicans hold a $322 million advertising advantage across the seven Senate toss-up races tracked by the Cook Political Report, according to AdImpact data compiled through mid-October. Democrats trail $625 million to the Republican total of $947 million in those contests. The gap narrows sharply in the 21 House toss-ups, where Republicans lead by only $14 million.
Early voting opened in Texas on October 19 and runs through October 30, with similar periods underway in Minnesota and other states. Campaigns are shifting resources accordingly: Republican groups have increased reservations in Kansas and Ohio while pausing buys in some North Carolina and New Jersey House districts. Democrats continue to allocate funds into districts that favored Trump in 2024.
Elon Musk’s contributions account for roughly $170 million directed to super PACs supporting Texas Republican Senate nominee Ken Paxton. Overall Senate spending in Ohio has already surpassed $420 million, the highest of any single race tracked by AdImpact. Trump has held multiple rallies in Ohio and Georgia in recent weeks.
Democratic candidates have raised more individual contributions than their Republican opponents in most Senate and House contests, giving them access to lower broadcast rates. Republican outside groups, however, retain the larger aggregate reserve. Cook Political Report has moved several House races toward Democrats in the past month.
No independent verification exists for final two-week spending totals or precise turnout projections in the states now voting early.
