- The 10 candidates hoping to fill Massachusetts' open 5th Congressional District U.S. House seat are making their final appeals ahead of Tuesday's primary.
Voters will be asked to winnow the field of seven Democrats and three Republicans down to a single candidate for each party.
The Democratic candidates include Belmont state Sen. William Brownsberger, Middlesex Sheriff Peter Koutoujian, Ashland state Sen. Karen Spilka, Melrose state Sen. Katherine Clark and Medford state Rep. Carl Sciortino.
Two other Democrats - former Lexington School Committee member Martin Long and Stoneham resident Paul John Maisano - are also running.
The three Republicans in the race are Boston attorney Frank Addivinola, Holliston resident Michael Stopa and Framingham veteran Tom Tierney.
They're all vying for the seat left vacant by Edward Markey's election to the U.S. Senate this summer.
