Voters in Maine, Nevada, South Carolina and North Dakota are voting in primaries ahead of the November 2026 midterm elections. Multiple outlets report that polling takes place across all four states on Tuesday, with the specific timing of polls varying by state. In Maine, the focus is on a Democratic U.S. Senate primary race featuring candidate Graham Platner, whose campaign faces scrutiny related to past controversies. Coverage describes that Platner seeks to overcome the scandals as the contest moves toward the general election season.

Elsewhere, primary voters in Nevada, South Carolina and North Dakota also head to the polls as part of the broader midterm election calendar. The reports frame these races as tests of candidate support and party positioning going into the 2026 elections. While the emphasis differs by outlet—particularly regarding Maine—the overall picture is that voters in four states are selecting party nominees through primary elections that feed into the November midterms.
