Voters on Tuesday will cast ballots in primaries in four states: Idaho, Nebraska, Oregon and Pennsylvania. The New York Times will have live results beginning Tuesday evening.
Idaho has seen tremendous growth recently, bringing changes to the economics, politics and demographics of a state that has long been dominated by Republicans. No one is expecting that dominance to change on Tuesday, but when The Times visited Boise recently, political analysts pointed to some local positions there that were competitive for the first time in recent history. Read what the residents had to say here.
Statewide, the main story is the race for governor.
Gov. C.L. Otter, a Republican popularly known as Butch, is retiring after 12 years. The leading contenders for the nomination to replace him are Lt. Gov. Brad Little, United States Representative Raúl Labrador and Tommy Ahlquist, a physician and businessman in Boise.
On the Democratic side, former State Representative Paulette Jordan is facing off against a longtime school board member, A.J. Balukoff.
Idaho has not had a Democratic governor since 1995.
In Oregon, Gov. Kate Brown is expected to prevail over two opponents in the Democratic primary, Ed Jones and Candace Neville. Ms. Brown, who has been in the office since 2015, won a special election in 2016 to finish out the last two years of her predecessor’s four-year term, and is now running for a full term herself.
A tighter race is shaping up on the Republican side, where State Representative Knute Buehler is facing off against Greg Wooldridge and Sam Carpenter.
Oregon, a liberal stronghold, has not had a Republican governor since 1987.
And in Nebraska, Senator Deb Fischer is up for re-election. She is running unopposed in the Republican primary. There are four Democrats competing for the chance to beat her in November.
In Pennsylvania, voters will cast their ballots for the first time under new district maps that were imposed by the state Supreme Court to combat partisan gerrymandering that favored Republicans.
Analysts expect Democrats to pick up as many as six seats in the House of Representatives in November, and Tuesday’s primaries will determine who those candidates will be.
Voters in the state will also choose candidates for governor and lieutenant governor.
The incumbent governor, Tom Wolf, a Democrat, does not have a primary challenger. On the Republican side, voters will choose between three candidates for governor: Laura Ellsworth, Paul Mango and Scott Wagner.
The race for lieutenant governor is crowded, with five Democrats and four Republicans seeking the job.

A quick recap of why Pennsylvania has a new map
The state Supreme Court ruled in January that Pennsylvania’s congressional map was an illegal partisan gerrymander that “clearly, plainly and palpably” violated the State Constitution.
The map, which was drawn after the 2010 census, favored Republicans, who repeatedly won 13 of the state’s 18 House seats under it. Pennsylvania voters support the two parties in roughly equal numbers.
The new map was imposed by the court in February after Mr. Wolf and the Republican-controlled state legislature failed to agree on how to draw a new one.
The court said the districts it drew “follow the traditional redistricting criteria of compactness, contiguity, equality of population, and respect for the integrity of political subdivisions.”
While the Pennsylvania map was redrawn by the state court, similar action may be looming at the federal level. The United States Supreme Court is considering two cases of partisan gerrymandering this session, one from Wisconsin that appears to favor Republicans and one from Maryland that appears to favor Democrats. It is expected to make a decision in those cases later this year.
