With the 2026 midterms in full swing, May is shaping up to be the busiest month of the primary season. From deep-red strongholds to critical “purple” battlegrounds, voters across more than a dozen states are heading to the polls this month to shape the future of Congress and state houses.

Whether you are watching the return of familiar faces or the rise of new challengers, here is your roadmap to the elections that matter this May.

Early May: Setting the Pace

The month kicks off with a flurry of activity in the Midwest and South, focusing on local leadership and statewide power dynamics.

• Texas (May 2): The month began with local races across the Lone Star State. These non-partisan municipal elections often fly under the radar, but they determine the leadership of Texas’s rapidly growing cities and school boards.
• Indiana & Ohio (May 5): Today marks a major shift to statewide stakes.
  • Ohio: All eyes are on the Senate and Governor races. Former Senator Sherrod Brown is attempting a high-profile comeback, facing newcomer Ron Kincaid in the Democratic primary. Meanwhile, the GOP field to succeed term-limited Gov. Mike DeWine features biotech entrepreneur Vivek Ramaswamy, who holds a significant polling lead.
  • Indiana: Republican primaries for state house and senate seats are the main event here, with several “Trump-endorsed” challengers looking to unseat incumbents.
• Michigan & Tennessee (May 5): Local elections and special general elections (including Michigan’s State Senate District 35) are also being decided today.

Mid-May: The Heart of the Heartland

As we move into the second week, the focus shifts to the Great Plains and the Appalachian mountains.

• Nebraska & West Virginia (May 12): Both states will hold their full statewide primaries. In Nebraska, keep an eye on the nonpartisan primary system for the state legislature, while West Virginia voters will be finalizing their tickets for key House seats.
• Louisiana (May 16): Louisiana typically holds its municipal primaries this weekend. Note that while many local races are proceeding, recent court challenges regarding redistricting have caused shifts in the scheduling of some congressional primary contests.

May 19: The “Super Tuesday” of Spring

Mark your calendars: May 19 is the biggest Election Day of the month. Voters in five states will head to the polls simultaneously, offering a massive snapshot of the national mood heading into the summer.

• Pennsylvania: As a premier swing state, Pennsylvania’s primaries for the U.S. House will be scrutinized for clues about voter turnout and enthusiasm in suburban districts.
• Georgia: Following years of intense political focus, Georgia’s primaries remain a central pillar of the 2026 map.
• Oregon, Idaho, & Kentucky: These states will also hold their primary elections, finalizing their candidates for the general election in November.

The Grand Finale: Texas Returns

• Texas (May 26): The month concludes where it began—in Texas. However, the stakes are higher this time. May 26 is Primary Runoff Day. In races where no candidate secured more than 50% of the vote during the March primaries, the top two finishers will face off for the final spot on the November ballot.

Why It Matters

May’s results will largely dictate the “flavor” of the 2026 general election. By the time June arrives, the matchups for the most competitive Senate and House seats in the country will be set.

Pro-Tip: Before you head out, double-check your local polling place and registration status, as some states have implemented new voting procedures or redistricted boundaries for this cycle.
