The town’s two major political parties will select their candidates for this year’s municipal election at nominating conventions in July, with a Republican primary for several slots likely in September.

Democrats will hold their caucus July 23 at 7 p.m. at McKinley School, while the GOP session will be July 21 at 7:30 p.m. at the Board of Education offices.

Republican Representative Town Meeting member Chris Tymniak is the only declared candidate seeking his party’s party nod to face off against Democratic First Selectman Michael Tetreau, who is seeking election to a second term.

At this point, it appears there will be a Republican primary for the selectman’s seat with Selectman Kevin Kiley seeking a full-term on the board, and another RTM member, Laurie McCardle, challenging him for that nomination.

Contests are also expected for Board of Education seats on the GOP side, Republican Town Committee Chairman James Millington said.

When McCardle recently announced her bid for the selectman’s nomination, Kiley issued a statement urging Millington to set up a debate between himself and McCardle at the next RTC meeting.

“Mr. Kiley had never called me to make this request,” Millington said, adding the agenda for that session was already set, but a candidate forum for contested offices will be held at the committee’s July 6 meeting.

Meanwhile, six Republicans have announced their intention to seek the nomination to run for a maximum of three seats on the school board. Millington said five will be endorsed for the November ballot.

Democrats are not expecting any contested seats, according to Democratic Town Committee Chairman Heather Dean. Selectman Sheila Marmion is seeking election to a full term on the board. Marmion and Kiley were both appointed to the board to fill vacancies.

“The Fairfield Democrats are very excited about the 2015 November elections,” Dean said, “and candidates interested in running are coming forward with enthusiasm.” However, Dean said, potential candidates have been told to make their own individual announcements, with a list of the official candidates available at the July nominating convention.

So far, in addition to Tetreau and Marmion, Board of Education Chairman Phil Dwyer has announced he will seek another four-year term.

Republicans running for a school board seat include: Jason Li, a Representative Town Meeting member; Anthony Calabrese, a Town Plan and Zoning Commission member; Laura Bernaschina, Patricia Donovan, Trisha Pytko and Carolyn Trabuco.

School board members whose terms expire in November include: Dwyer, the board chairman, and fellow Democrats Jessica Gerber and Jennifer Maxon-Kennelly, and Republicans Paul Fattibene and John Convertito, the vice chairman.

Republicans Jim Brown and James Walsh are seeking re-election to the Board of Finance. Brown is currently the panel’s vice chairman. Democrat Tata Cook-Littman’s seat on the finance board also expires in November.

“The candidates are working hard to win the support of the RTC membership,” Millington said. “I am very pleased by the quality of the candidates who have come forward offering to serve and give back to their community.”

Should a primary be necessary, it will take place Sept. 16, a Wednesday because of the Labor Day and Jewish holy day observances.
