With the primary field set for Maryland’s 6th Congressional District, Republican voters have a choice between two candidates with past primary election success and four relative newcomers to politics. Neil Parrott, a state delegate from 2011 to 2023, filed Friday — deadline day — for the Republican primary after months of mulling it over. Parrott previously won the Republican primary for the seat in 2020 with 65% of the vote and again in 2022 with 63%.
