Sen. Elizabeth Warren said Democrats will win in November despite record "dark money" spending, citing the 2026 primaries as proof that grassroots organizing still matters. A New York Times review found roughly $1 billion in anonymous funds shaping major races. In Michigan, Abdul El-Sayed narrowly beat Rep. Haley Stevens after overcoming more than $60 million in opposition spending and mobilizing about 12,000 volunteers. Polymarket now gives Democrats a 61% chance to take both the House and Senate, up from 49% a month ago.

Sen. Elizabeth Warren (D-Mass.) voiced confidence Sunday that Democrats will prevail in the November 2026 midterms, despite a surge in anonymous spending in this year's races.
A New York Times analysis of ad data, campaign filings and tax records found roughly $1 billion in "dark money" has influenced — or is expected to influence — many major primaries and battleground contests this cycle. Warren warned that outside groups tied to technology, cryptocurrency and foreign policy interests have poured millions into races, but argued grassroots organizing still matters.
“Dark money groups are pouring record sums into our elections. But the 2026 primaries have shown that when people organize and show up, billionaires don't get to decide who wins. Grassroots power still matters. And we will in November.” — Elizabeth Warren (@ewarren)
Warren pointed to recent primary upsets as evidence. In Michigan, Abdul El-Sayed narrowly defeated Rep. Haley Stevens (D-MI) in the Democratic Senate primary by less than one percentage point. Coverage credited El-Sayed's campaign with driving record turnout, overcoming more than $60 million in opposition spending and mobilizing roughly 12,000 volunteers to secure the victory.
