/ Mary Nogami sees herself as an extremism-neutralizer. In her majority-GOP Bucks County community, Nogami, 47, who voted for President Joe Biden, sees a split between Republicans who have doubled down in their support of former President Donald Trump and more moderate conservatives. She changed her registration to Republican in February of this year “to help that party, hopefully, from the inside.” And she has watched as existing fault lines in the community have influenced the tone of local races ahead of the May 18 primary. “The community being so torn, it probably comes from the stress of the pandemic, the stress of the 2020 election,” said Nogami, of Hilltown Township.
