CNN: Republicans are in a tough race to hold on to dozens of House seats and several key Senate seats, as voter discontent grows over rising prices and a deeply unpopular war with Iran, with neither issue showing a clear prospect of ending the crisis.
With three months until the US midterm elections, the races in both the House and Senate are close, and both Trump and Democrats are struggling with low support.

House Republicans ‘in the strongest position’ ever 100 days from midterms: Memo
AM: 100 DAYS OUT: HOUSE GOP IN DANGER ZONE • • Sunday is 100 days ahead of the midterm elections. The House is gone for five weeks. And things are looking bleak for the House Republican majority. • • Two congressional generic ballots from July showed Democrats up by seven and 11 points. Gas prices have soared to more than $4 per gallon again — and they’re heading higher as the unpopular Iran war grinds on. • • President Donald Trump’s approval rating is stumbling along at record lows, while interest rates are up and inflation remains elevated. Trump launched yet another new tariff regime on Thursday night. Young people can’t find jobs even though unemployment is low. Polling shows voters trust Democrats more on nearly every major issue from immigration to the economy. • • Plus, midterm history is against Republicans. The Democratic base is very motivated to vote against Trump and the House GOP majority is historically small. Democrats will only need to net four seats to win. • • There are bright spots for the GOP, and we’ll get to those. • • Yet let’s also look at what the House Republican majority did in its final substantive legislative stretch before Election Day. Republicans passed a voter ID law that looks DOA in the Senate while also approving a framework to spend billions of dollars more on the Iran war. • • We’ll note that the GOP thinks they’ll be able to use Democratic votes against a stock-trading ban and voter ID bill in TV ads regardless of whether they pass the Senate. And some Democrats want to make sure the troops are funded even if they’re against the war. • • But overall, the House Republican majority — roiled by retirements, shutdowns, scandals and infighting — is ripe to disappear. Yet can Democrats, who are pretty unpopular themselves, find their way into the majority? And if so, by what kind of margin? • • • • @allymutnick @maxpcohen

Pair it with this Fox News poll, which has the generic at D+7 -- also a big gulf on the generic. • • "If the election were today, 53% of voters would back the Democratic candidate in their House district and 46% the Republican. That 7-point edge is just outside the poll’s margin of error. Democrats were up by 5 points in April. Notably, 53% is the highest percentage either party has received on the generic House ballot in Fox News polling since 1996." • •

There are midterms where this is holding up until October, then the bottom falls out for the president's party (2006, 2014); there are midterms where the in-party actually makes it a choice, not a referendum and it holds through voting (2018 in Senate, 2022).

What is this event about?

This market will resolve according to the popular vote margin of victory between the Democratic Party and the Republican Party in the US House of Representatives midterm elections, scheduled for November 3, 2026. For the purpose of this market, the “popular vote margin of victory” is defined as the absolute difference between the percentage of valid votes cast for all Democratic Party House candidates and the percentage of valid votes cast for all Republican Party House candidates in this election. The percentage of the valid votes cast for each party’s House candidates will be determined by dividing the total number of valid votes that party’s House candidates receive by the sum of all valid votes cast for U.S. House candidates in the election. Only votes cast for candidates for U.S. Representative (voting members of the House of Representatives from districts in the 50 states) will be considered; votes for Delegates and the Resident Commissioner will not be considered. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. This market will resolve based on the vote totals as published by the US Clerk of the House. Any recount included in the Clerk of the House’s publication will be considered. If the US House of Representatives midterm elections do not take place by June 30, 2027, 11:59 PM ET, this market will resolve to "Other". The resolution source for this market will be 2026 midterm election results published by the US Clerk of the House (https://history.house.gov/Institution/Election-Statistics/). If the 2026 midterm elections take place, and the Clerk of the House does not publish the results of this election by June 30, 2027, 11:59 PM ET, another credible resolution source may be chosen.
