The Latest: Walker wins Delaware GOP House primary race

DOVER, Del. (AP) — The Latest on Delaware's primary election (all times local):

9:25 p.m.

Scott Walker, a business owner and landlord who ran unsuccessfully for Congress as a Democrat two years ago, has won the Republican primary for Delaware's lone U.S. House seat.

The 67-year-old Walker defeated actor and retired railroad industry worker Lee Murphy on Thursday and will face incumbent Democrat Lisa Blunt Rochester in November.

Blunt Rochester easily won a six-way Democratic primary for Congress in 2016. Walker finished fifth in that race with less than 5 percent of the vote.

Walker's political fortunes changed after he switched parties. During the campaign, Walker stressed the need to improve the nation's defense, economy and health care system. He also noted that he recently became very religious, and that he has God on his side to help conquer every problem.

Rob Arlett, a county councilman who served as Donald Trump's state campaign chair in 2016, has won the Republican primary for U.S. Senate in Delaware.

The 51-year-old Arlett defeated former PayPal executive Gene Truono in Thursday's primary.

Arlett, who owns a real estate business, has served on the Sussex County council since 2015.

During the Senate campaign, Arlett touted his support of Trump's "America First" agenda and his socially conservative positions, including opposition to abortion and gay marriage. He reminded GOP voters that Truono is openly gay and in a same-sex marriage.

Arlett also called for repeal of the Affordable Care Act and defunding of so-called "sanctuary cities."

Incumbent Tom Carper has won the Democratic U.S. Senate primary in Delaware as he eyes a fourth term in the Senate.

The 71-year-old lawmaker defeated 38-year-old political newcomer Kerry Evelyn Harris in Thursday's primary contest.

With the win, Carper keeps his unbeaten streak intact, having never lost an election since his first campaign in 1976.

Harris is among a wave of young activists emboldened by the 2016 presidential campaign of U.S. Sen. Bernie Sanders of Vermont who have been trying to move the Democratic Party farther left. Her platform included government-paid health care for all, a $15 hourly minimum wage and abolishing the federal Immigration and Customs Enforcement agency.

Carper will face the winner of the Republican Senate primary between Gene Truono and Rob Arlett in November.
