Recent midterm developments: Dems lead early ballots cast in 8 key Senate states; GOP leads in 6

• National: 54.8mln early ballots cast (56% in person); registered Dems lead D+11 (46%-35%), and D+15 on mail ballots requested/sent.
• Senate battlegrounds: 18.5mln cast, mostly in person (~83%); Dem lead narrower at D+5 (45%-40%), D+12 on mail ballots.
• Dems lead early ballots cast in 8 key Senate states (OH D+3 to MN D+28); GOP leads in 6 (AK R+9, NE R+5, KS and FL R+3, TX R+2, SC R+1).
• NEC Director Hassett says US President Trump won't sign any bills that reverse his policies; Trump vows to be "Mr Veto" if Democrats retake the majority.
• The White House has been preparing since April for a possible Democratic takeover of Congress, according to Reuters, citing sources: officials are identifying executive actions Trump could take without Congress, including tariffs on critical minerals and wind turbines, tighter student and foreign-worker visa rules, housing-cost measures, and using already-appropriated funds and changed grant rules to steer spending.
• Rep. Haley Stevens, who lost Michigan's August Democratic Senate primary to Abdul El-Sayed, endorsed Republican Mike Rogers on Sunday. She had demanded El-Sayed condemn a supportive PAC's ad she called antisemitic, apologise for past Israel comments and pull a Tucker Carlson ad. El-Sayed said it didn't matter, and Polymarket still gives him an 80% chance of winning.
• US District Judge Sharon Gleason in Anchorage, Alaska, on Sunday dismissed a Trump administration lawsuit seeking to stop Alaska from certifying a loss by Republican Sen. Dan Sullivan in Tuesday's election if votes for a rival candidate who shares his name could have changed the outcome.
• US District Judge Trina Thompson on Friday issued a temporary restraining order barring the DoJ from threatening to prosecute state and local election officials who don't comply with Trump administration demands over alleged non-citizen voting, in a suit brought by election workers' unions and other groups. The order also bars the administration from demanding officials remove voters from rolls, refuse ballots to specific voters or segregate ballots based on its list of alleged non-citizen voters.
• The Trump administration asked the Supreme Court on Monday to block California from counting about 20,000 mail ballots it says may come from non-citizens. The move follows the 9th Circuit's 2-1 ruling against the DoJ on Friday. The panel said there was "no feasible way to identify and segregate the ballots of specific individuals without potentially catastrophic effects on the entire system."
• The final NBC News poll (October 28th-30th, registered voters) showed Democrats leading Republicans 52%-45% on the generic congressional ballot, up 2 points from last month, including a 21-point lead among independents, with 3% undecided. Trump's disapproval hit 60%, a high across both his terms. About three-quarters of voters are dissatisfied with the economy, 70% say the country is on the wrong track (up 9 points in a year), 64% say Trump has fallen short of expectations, and for the first time in 30 years of NBC polling, more voters are dissatisfied (51%) than satisfied (49%) with their personal finances.
• The final NYT/Siena polls of likely voters (October 23rd-November 1st) showed Democrats leading outside the margin of error in five key Senate races. Michigan, El-Sayed 53% vs. Rogers 42%; Texas, Talarico 50% vs. Paxton 43%; Maine, Jackson 51% vs. Collins 45%; Ohio, Brown 49% vs. Husted 44%; Kansas, Hamilton 49% vs. Marshall 44%. Alaska (Peltola 48%, Sullivan 46%) and Iowa (Turek 48%, Hinson 47%) are within the margin of error.

Early-vote data of this kind has a well-documented limitation: party registration of ballots cast measures turnout composition, not vote choice, and its predictive value has historically weakened as the two parties have alternated between encouraging and discouraging mail voting, so the registered-Democrat edge is a softer signal than the topline implies. The more substantive thread is the veto pledge and the reported contingency planning for a hostile Congress; on past occasions when an administration has anticipated losing a chamber, the standard sequence has been a pivot from legislation to executive action, with tariffs, visa rules and grant conditions as the instruments least exposed to congressional reversal, and that pattern is what the reported planning describes. The transmission channel in such episodes has tended to run through sector-specific policy risk (the industries named in executive orders) and through fiscal expectations at the long end, since divided government has historically implied legislative gridlock rather than new stimulus. The litigation cluster around certification and ballot challenges is the familiar tail risk: past contested counts have moved markets only when they threatened the orderly transfer or seating of power, and court action in the days immediately surrounding an election has typically been resolved before becoming market-relevant. The near-term calendar is the count itself and any post-election legal escalation; the prior form on both is that early-count ambiguity resolves faster than headlines suggest.
