Three Republicans who want to flip a highly competitive Congressional seat in Maine think the key to winning is to appeal to fans of President Donald Trump in rural parts of the state.

Former state Sen. Eric Brakey, realtor and former television news reporter Adrienne Bennett and former state Rep. Dale Crafts all want to unseat Democratic Rep. Jared Golden in Maine’s 2nd Congressional District.

The vast, mostly rural district is the largest Congressional district east of the Mississippi River, and Trump won it decisively in 2016. His poll numbers have dipped in recent months, though.

The three Republicans face each other in the July 14 primary.
