Ohio and Indiana mark the beginning of a particularly rugged stretch in the midterm campaign, littered with bitter and costly primary elections that will help determine control of Congress and the governor’s offices.
Some states don’t hold their primaries until September, including New Hampshire, which has a hard-fought Senate race.
Circle this data:
May 17: Pennsylvania and North Carolina
In Pennsylvania, a race for an open Senate seat will play a key role in deciding whether Democrats retain control of the chamber. The GOP field is headed by the famous doctor Mehmet Oz.
In North Carolina, the impending resignation of Senator Richard Burr, a Republican, has drawn a crowd of candidates.
May 24: Georgia
Georgia, which helped Democrats flip the Senate in 2021 and gave Joseph R. Biden Jr. a win in 2020, features marquee competitions for governor and Senate. Stacey Abrams, a Democrat running for governor, is back. And the foreign minister’s race is also remarkable.
June 14: Nevada
The last time Catherine Cortez Masto, the first Latin American senator, stood on the ballot, outside groups flooded Nevada with more than $90 million. Now she is up for re-election.
Adam Laxalt, a former Nevada attorney general who ran unsuccessfully for governor in 2018, has to get past the GOP primary to challenge her.
August 2: Arizona and Michigan
Arizona has emerged as one of the top prizes this year, with an open seat for governor and a hard-fought Senate race. The Senate seat is held by Mark Kelly, a Democrat who won a special election in 2020 to fill the seat once held by John McCain.
In Michigan, Gov. Gretchen Whitmer, a Democrat and at the center of Conservative anger over pandemic restrictions, is running for re-election. In addition to picking a gubernatorial nominee, Republicans are grappling with internal tensions and the influence of former President Donald J. Trump, who made a series of recommendations at House races.
Both states also have notable secretaries of state.
August 9: Wisconsin
Wisconsin has bipartisan potential, with gubernatorial and senate contests attracting a crowded field of candidates.
Sen. Ron Johnson, a Republican whose approval rating has plummeted as TV ads bombard him with criticism for expressing doubts about Mr. Biden’s election, is a prime target for Democrats. Republicans are focused on taking the seat of Governor Tony Evers, a Democrat.
September 13: New Hampshire
The winner of the GOP Senate primary will have less than two months to launch a general election campaign against Senator Maggie Hassan, a Democrat believed to be vulnerable.
