CAPE ELIZABETH — Democratic state Sen. Cynthia Dill of Cape Elizabeth and Secretary of State Charles Summers Jr., R-Scarborough, on Tuesday won their parties’ nominations for the U.S. Senate.

By late Tuesday, national and state media outlets had called the race for Dill and Summers, with roughly 88 percent of precincts reporting. 

The two partisans will face former independent Gov. Angus King, who is running as an unenrolled candidate and is widely seen as the front-runner, as well as a handful of other unenrolled candidates. 

According to the Bangor Daily News, Summers had 30 percent of the Republican vote in a six-way race. Runner-up Bruce Poliquin, the current State Treasurer, from Georgetown, had 22.6 percent of the vote, followed by former Senate President Richard Bennett of Oxford, with nearly 18 percent.

Figures Wednesday morning showed Dill leading the four-way Democratic primary with nearly 45 percent of the votes, trailed by former Secretary of State Matthew Dunlap of Old Town, with 35 percent.

Andrew Ian Dodge, a conservative activist from Harpswell, businessman and Yarmouth Town Council Chairman Steve Woods and Brunswick resident Danny Dalton are also running for the U.S. Senate seat.

By Wednesday afternoon, state Senate majority leader Jonathan Courtney, R-Springvale, appeared to have won a slim victory over Portland merchant mariner Patrick Calder in the GOP primary for Maine’s 1st Congressional District.

According to the Bangor Daily News, Courtney beat Calder by just 276 votes. The race was too close to call by late Tuesday night, and results continued to trickle in Wednesday morning. 

Courtney will face incumbent U.S. Rep. Chellie Pingree, D-North Haven, in November’s general election.
