The democrat who challenged incumbent congressman Paul Mitchell in last year’s election cycle will be making another run for the position in 2020. Kimberly Bizon is expected to announce today that she will be seeking her party’s nomination for the 10th congressional district. Bizon is an environmental activist who lives in Lexington. Earlier this year Congressman Mitchell announced he will not be seeking another term in office. Two republican candidates, Shane Hernandez and Doug Slocum have already announced their candidacy for the seat. Bizon is the first democrat to do so.
