A Trump-endorsed Republican candidate for governor opened a campaign office on Warren Street last Saturday. Geoff Diehl’s Waltham office is one of two statewide.

The Whitman Republican, 52, was not at the event, but his running mate for lieutenant governor, registered nurse Leah Allen, 33, was present alongside campaign staff and supporters. 

Diehl campaign spokesperson Peggy Rose said the location near 128 contributed to the decision to open an office in Waltham, offering “flexibility to engage more volunteers across the region.”

Among supporters at the event were Renee Arena [in green coat], a former Waltham school committee candidate and conservative voice opposed to various COVID mandates.


Republican governor Charlie Baker is not seeking re-election this fall. 

Diehl looks likely to earn the Republican nomination at the state GOP convention later this month, but polls favor Democratic Attorney General Maura Healey in November.

The former state rep was Donald Trump’s Massachusetts campaign co-chair in 2016. Diehl was endorsed by the former president for Massachusetts governor in October. 

Trump called Diehl “a true patriot, a believer in low energy costs and…strong on Crime, Election Integrity, our now under siege Southern Border, loves our Military and has a big focus on taking care of our Vets.” 

A married father of two, Diehl was first elected to the State House in 2010. He made a name for himself in 2014 during a successful grassroots effort to repeal a law that linked gas taxes to inflation.

Diehl has campaigned in Waltham several times in recent years.

He lost a U.S. Senate race by a large margin to Elizabeth Warren in 2018. During the campaign, he hosted a fundraiser with former Maine governor Paul LePage that drew protestors to The Chateau.
