Polls opened at 6 a.m. today in Fairfield and across the state for voters registered with the Democratic and Republican parties to choose their respective standard-bearers for an open U.S. Senate seat in November. Voting continues until 8 p.m.

There also is a local contest for the Democratic nomination in the 132nd House of Representatives district.

Poll workers in Fairfield said voter turnout has been steady, though not tremendously high. By 11 a.m., Republican Registrar of Voters Roger Autuori said he still had some districts where fewer than 100 voters had cast ballots.

With primaries in both parties, the polling stations have separate check-ins for each party and their own moderators. Without enough electronic ballot scanners for each district to have two, Autuori said he made the decision to use wooden ballot boxes to collect the Republican votes, which will be later tallied by hand.

Seeking the Democratic Senate nomination is U.S. Rep. Chris Murphy, the endorsed candidate, who is being challenged by former Secretary of the State Susan Bysiewicz.

The endorsed Republican Senate candidate is Linda McMahon, former executive with World Wrestling Entertainment, who is taken on by former U.S. Rep. Christopher Shays.

In the Democrats' 132nd House primary, Sue Brand, a Board of Education member and endorsed candidate, is being challenged by Kevin Coyner, a newcomer to Farifield politics who works as a Greenwich firefighter.

Republican Jennifer Landgraf showed up at the polling station in the Fairfield Museum and History Center with sons William, 2 and a half, and 1-year-old Drew. "I'm just proud to have the opportunity I guess and I just care about the future of our state and country," she said.

Landgraf said she'd be a Democrat "if they can meet me in the middle of the financial stuff and foreign policy." She said she leans more Democratic on things like civil-rights issues. "It always comes down to what are your top priorities," Landgraf said. "The things that are most important to me are more aligned with the Republicans."

The number of registered Democrats in Fairfield eligible to vote in the primary is 9,836, while the number of voters registered with the GOP eligible to cast ballots in that primary is 10,333.

The town's 14,338 unaffiliated voters and the 199 voters registered with other political parties cannot vote in any of the primaries.
