For the second time since 2004, Greer Tan Swiston is taking on Democratic state Representative Kay Khan for the House of Representatives seat Khan has held for almost 20 years.

Both candidates are well known in their district, which covers half of the City of Newton, including the villages of Newton Lower Falls, Auburndale, Waban, West Newton, Newtonville, Newton Corner, and parts of Newton Centre, and they bring stark political differences to the Nov. 6 general election.
