President Donald Trump backed two successful U.S. Senate nominees in Pennsylvania and Nebraska, which were among four states holding primaries Tuesday.
The primaries began to settle swing state Pennsylvania's chaotic congressional landscape after a court fight ended with redrawn districts just three months ago. Amid the redistricting, Republican Rick Saccone recorded his second loss in two months in two U.S. House districts.
Among the more unusual results of Tuesday's primaries was the loss by Pennsylvania's Democratic lieutenant governor, Mike Stack, who was ousted by mayor John Fetterman.
Oregon and Idaho also held primary elections.
Here's a look at some of the other interesting races:
TRUMP'S PICKS PREVAIL
Two of the president's favored candidates, Lou Barletta in Pennsylvania and Deb Fischer in Nebraska, won their U.S. Senate primaries.
Trump congratulated his picks in a pair of tweets Wednesday morning.
Barletta, currently a congressman, was heavily favored over state Rep. Jim Christiana to become the Republican challenger for Democratic Sen. Bob Casey, who is seeking a third term in November.
Barletta was a Trump supporter before the 2016 presidential nomination was settled. Trump asked Barletta to run for Senate, and the president is expected to visit Pennsylvania to campaign for him. The president also recorded telephone calls last weekend backing Barletta "fully, strongly and proudly."
Fischer, the incumbent, defeated four GOP challengers and will be the strong favorite to win re-election in deep-red Nebraska. Her Democratic opponent is Lincoln City Councilwoman Jane Raybould.
Last week, Trump urged GOP Senate primary voters to support Rep. Jim Renacci in the Ohio Senate and oppose former coal company executive Don Blankenship in West Virginia. Renacci won and Blankenship lost.
WOMEN RULE IN REDRAWN DISTRICTS
Pennsylvania could send at least three women Congress next year, breaking the all-male hold on the state's 18-member U.S. House delegation.
Mary Gay Scanlon won a 10-way Democratic primary and Madeleine Dean won a three-way Democratic primary on Tuesday night for two suburban Philadelphia seats that are likely to flip to Democrats following a court-ordered redrawing of the state's congressional district boundaries.
Meanwhile, Chrissy Houlahan is the uncontested Democratic nominee for another suburban Philadelphia seat where she's heavily favored in November.
Women won contested Democratic primaries in three other seats in Pennsylvania, although two of those seats are in solidly Republican districts and another is considered a toss-up in November.
INCUMBENT LIEUTENANT GOVERNOR FALLS
Mike Stack became the first holder of the Pennsylvania lieutenant governor's office to lose in a primary election.
John Fetterman, the Braddock mayor, won the five-way Democratic Party primary race for lieutenant governor Tuesday, meaning 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.
Fetterman had made a failed bid in 2016 for the U.S. Senate.
Stack, a former Philadelphia state senator, has had a chilly relationship with Wolf in their first term together.
Wolf last year ordered an investigation into the treatment of state employees by Stack and his wife and stripped Stack of state police protection.
SECOND LOSS IN TWO MONTHS FOR SACCONE
Pennsylvania state Rep. Rick Saccone, who lost a special election two months ago to Democrat Conor Lamb for a congressional seat, has now lost a two-way Republican primary for a different U.S. House seat.
Saccone lost Tuesday's 14th Congressional District primary election to state Sen. Guy Reschenthaler for the open seat in a heavily Republican, newly drawn district.
