Moderate Democratic Rep. Ed Case, D-Hawaii, fended off a primary challenger in the state’s elections Saturday, setting himself up for a likely sixth full term in the House of Representatives.

Case is running for the seat in Hawaii’s 1st Congressional District, which he’s held since winning in the 2018 midterm elections.

He first came to Congress as a representative for the island’s 2nd Congressional District, winning a special election to fill the seat of Rep. Patsy Mink, who died of pneumonia in 2002.

HAVE BATTLEGROUNDS SHIFTED WITH HARRIS AT TOP OF TICKET?

Case left the House of Representatives in January 2007 and returned in January 2019, representing his current district.

He made headlines just last month as one of dozens of House Democrats who called on President Biden to drop out of the 2024 presidential race, which Biden did later that month.

In a July 11 statement, Case maintained that his decision only came from concerns about the 81-year-old leader’s ability to carry out another four-year term.

"This has nothing to do with his character and record," Case said at the time. "If it did, there would be no decision to make."

Case is no stranger to crowded primary elections, besting a field of 44 candidates to replace Mink for her final two months in office in 2002. He also won a seven-way primary for his current seat in 2018.

This time, however, he faced just one primary challenger, Cecil Hale, who does not appear to have disclosed campaign finance data to the Federal Election Commission.

Case, by contrast, raised nearly $120,000 in individual contributions and ended the primary cycle with almost $260,000 cash on hand.

18 DAYS: KAMALA HARRIS HAS NOT HELD A PRESS CONFERENCE SINCE EMERGING AS PRESUMPTIVE DEMOCRATIC NOMINEE

Hawaii only has two congressional districts, both represented by Democrats, and both of its senators are also Democrats.

It’s a safe blue stronghold for the left despite pervasive issues like the high cost of living, which has traditionally been a potent political weapon for Republicans in other parts of the country.

Republican Patrick Largey is running unopposed for the Republican nomination to challenge Case in November.

Sen. Mazie Hirono, D-Hawaii, easily won her primary race on Saturday, setting Democrats up for a likely victory in November.

She was up against Clyde Lewman, a wood products salesman, and Ron Curtis, a retired engineer. 

Curtis was last up against Hirono in 2018 as the Republican nominee for her Senate seat. He lost to the incumbent Democrat by about 29% to 71%.

He also challenged Rep. Ed Case, D-Hawaii, for his House seat in 2020, but lost by similar margins.

Hirono, a progressive, is seeking a third six-year term representing the majority-left-wing island state.

The Japan-born U.S. senator is the favorite to win Hawaii’s general election later this year. But her victory will be much welcomed among Democrats as they fight what could be an uphill battle to keep their razor-thin majority in the Senate.

Her 2024 campaign brought in more than $3 million in individual donations, according to campaign finance data. The Federal Election Commission site did not have records of her opponents’ fundraising.

Hirono was the lieutenant governor of Hawaii before being elected to the U.S. House of Representatives, where she served three terms prior to her 2012 run for Senate.

Hawaii’s congressional delegation, two senators and two House members, is fully Democratic.

The state’s governor’s office and both houses of its state legislature are also controlled by Democrats.

Democrats are likely to pad their numbers with Hirono's expected victory in November in a Senate map where they're at risk of losing critical races elsewhere, including ruby-red West Virginia.
