SACO — Saco voters returned former Mayor Mark Johnston to the mayor’s office over challenger Jeffrey Christenbury in balloting Tuesday.

Johnston received 3,249 votes to Christenbury’s 2,255.

“Thank you,” Johnston said to voters after learning the results. “I’m looking forward to doing the job for another two years.”

Incumbent Ward 7 Councilor Marston D. Lovell held on to defeat Nathan Johnston, Mark Johnston’s son, who was making his first run for the City Council. The vote was 317-270.

Christenbury, who had represented Ward 4 before moving out of the ward earlier this year, ran against Johnston, a former mayor who has served a total of six terms.

The incumbent mayor, Roland Michaud, stepped aside to seek a seat on the Regional School Unit 23 board of directors.
