Geoff Diehl, the republican candidate opposing Elizabeth Warren for a spot in the state senate, visited Dartmouth on September 14.

Diehl, who lives in Whitman, has served as the state representative for the seventh Plymouth district, which includes Abington, East Bridgewater, and Whitman, since 2010.

His proudest accomplishments include defeating the index gas tax and working to keep the Olympics from coming to Boston, as the Olympics are frequently extract a high cost from taxpayers.

“I’m trying to keep the government accountable and make sure that promises made are promises kept,” Diehl said.

Diehl alleges that current senator Elizabeth Warren puts her own political interests ahead of those of her constituents.

He said that if he was elected, he would put Massachusetts residents first, although “a U.S. senator can certainly have a voice in national politics.”

Diehl boasts endorsements from figures including Sean Spicer, Newt Gingrich, and Captain Dave Marciano of the TV show “Wicked Tuna.”

Among his top legislative priorities are supporting the fishing industry, fighting the opioid epidemic, supporting law enforcement, resisting tax increases, and reforming immigration policies.

“I think anyone who wants to come to the United States should be able to,” Diehl said. “Congress has been negligent in creating a system for allowing people to enter and assimilate.”

He noted that he has filed language at the State House to speed up immigration processes.

However, he has also been endorsed by Sheriff Thomas Hodgson and says his views on immigration are largely aligned with those of the Sheriff.

Diehl said that improving border security is important because it would “remove the temptation” of illegal entry and reduce drug and human trafficking by creating secure entry points.

Diehl will be up for election on November 6. Early voting will run from October 22 to November 2. The deadline to register to vote in this election is Wednesday, October 17.
