Voters went to the polls Tuesday in primary contests in four states: Pennsylvania, Nebraska, Idaho and Oregon. "Our right to vote is so critical, especially in these really challenging times," voter Elaine Petrossian told CBS Philadelphia.
Here are the results as they are coming in:
Pennsylvania is a must-win state for Democrats if they want to take back the House, CBS Pittsburgh money and politics editor Jon Delano told CBSN Tuesday. President Trump turned the state red in 2016 and it has for years been overwhelmingly Republican in the House, but new districts have Democrats hopeful the state is in play.
Four-term U.S. Rep. Lou Barletta, a staunch supporter of Mr. Trump who first got national notice as a small-city mayor for his attempted crackdown on illegal immigration, on Tuesday won the Republican nomination for U.S. Senate in Pennsylvania.
Barletta had paid little attention to his Republican rival, state Rep. Jim Christiana, during the primary campaign. Instead, he focused his attacks on the candidate he hopes to unseat in the fall, two-term Democratic Sen. Bob Casey.
Barletta is a favorite of Mr. Trump, whom Barletta endorsed in 2016. Mr. Trump asked Barletta to run for Senate, and the president is expected to visit Pennsylvania to campaign for him.
Casey, who was unopposed for the Democratic nomination, has opposed Mr. Trump's Supreme Court pick, many of his highest-profile nominees and the GOP tax-cutting law. He is among 10 Democratic senators seeking re-election this year in states won by Mr. Trump, making Casey a target for Republicans.
Mr. Trump edged Democrat Hillary Clinton by less than 1 percentage point in Pennsylvania in 2016's presidential election. Republicans control the Senate, 51-49, and defeating Casey would give Republicans one more vote favorable to Mr. Trump to help advance the president's agenda. But it is a tall order.
Casey, the son of a late former governor, has strong name recognition and has won five statewide elections, including two as auditor general and one as state treasurer. He also has a huge cash advantage, with about $10 million in the bank at the end of April, compared with Barletta's $1.3 million.
Casey, 58, is popular with labor unions and backed former President Barack Obama's signature policies.
Barletta, 62, won his House seat during the Republican midterm wave of 2010, catapulted by the attention he received while mayor of Hazleton for attempting to use local laws to crack down on immigrants in the city who had entered the country illegally.
In the gubernatorial race, Pennsylvania state Sen. Scott Wagner will run against Democratic Gov. Tom Wolf after winning the GOP primary, CBS Philadelphia reports. Wagner defeated two first-time candidates from the Pittsburgh area, Paul Mango and Laura Ellsworth, surviving weeks of Mango's sharp-elbowed attack ads that painted Wagner as sleazy, greedy and a "deadbeat dad."
Pennsylvania's lieutenant governor has become the first holder of the office to lose in a primary election.
John Fetterman won the five-way Democratic Party primary race for lieutenant governor Tuesday, beating incumbent Mike Stack.
The Braddock mayor's victory means he will run on a ticket with Gov. Tom Wolf in the fall. Pennsylvania first started allowing lieutenant governors to serve a second term in the 1970s.
