Registered Democratic and Republican voters head to the polls August 14 to determine party candidates for statewide offices—including governor—a number of state House and Senate races, and two U.S. congressional seats.
Polling places across the state will be open from 6 am to 8 pm. To be eligible to vote in party primary elections, you must be registered as a Democrat or Republican voter.
There is a three month waiting period to switch party affiliation. Unaffiliated voters are not eligible to vote in party primaries, but can enroll with either party at any time to vote in the primaries.
Connecticut has seen an unprecedented surge in voter registration—over 275,000 residents—since the 2016 elections.
As of June this year, there were 760,672 registered Democratic voters in Connecticut and 446,265 registered Republicans.
Independent or unaffiliated voters represent the largest voting bloc in the state—more than 143,000 people registered as unaffiliated since the 2016 elections, bringing the total number of independent voters to 857,111.
No contest will be more closely watched this year than the race to succeed Democratic Governor Dannel Malloy, who is not seeking reelection after two terms in office.
The August 14 primaries will determine which of two Democrat and five Republican hopefuls move on to the November 7 general election as their party's candidate.
Greenwich business executive Ned Lamont and Bridgeport Mayor Joe Ganim are on the Democratic Party primary ballot.
Lamont was endorsed at the party's May convention, while Ganim successfully collected the 15,000-plus signatures needed to win a spot on the ballot.
Danbury mayor Mark Boughton is the endorsed Republican candidate, while former Trumbull first selectman Tim Herbst and Westport tech entrepreneur Steve Obsitnik both earned enough convention support to qualify for the primary.
Former Greenwich hedge fund manager David Stemerman and Madison business executive Bob Stefanowski petitioned their way onto the primary ballot after skipping the Republican convention in May.
“Most folks on both sides don’t think Connecticut is working,” says one candidate for the state's highest office. Says another: “It’s puzzling as to how and why and where we lost our way, but we lost our way.” https://t.co/qgRJEmCf4C #Election2018 #ctpolitics

State Senate Primary Elections
Democratic candidates in five state Senate districts—in Fairfield, Hartford, Middlesex, and New Haven counties—face primaries to determine who will represent the party in the general election.
State representatives Tony Guerrera (Rocky Hill) and Matt Lesser (Middletown) are challenging for the 9th Senate District seat left vacant following incumbent Paul Doyle's decision to run for attorney general. Guerrera is the endorsed candidate.
Former state representative Vickie Nardello won a court decision to join party-endorsed candidate Dagmara Scalise on the ballot in the 16th Senate District.

State House Primaries
Five incumbent Democratic state representatives face primary battles, among the party's 10 state House district primary elections on August 14.
In Hartford, Minnie Gonzalez, who has held the 3rd House District for 22 years, is challenged by gay rights activist Gannon Long.
Two-term incumbent Brandon McGee lost the party's endorsement for the Hartford-based 5th House District to primary challenger Lawrence Jaggon, a Windsor nurse.
In West Hartford, non-profit director Jillian Gilchrest is challenging Education Committee co-chair Andy Fleischmann, who has held the 18th House District seat since 1995.
Three-term incumbent Charlie Stallworth will contest a primary in the 126th House District against former Bridgeport Housing Authority commissioner Shanté Hanks, who also earned the party's endorsement.
Incumbent Terry Adams' bid for a third term representing the Stamford-based 146th House District is far from certain after losing the local party's endorsement to environmental activist David Michel.
There are four Republican state House primaries—Bridgeport (128th District), Middletown (100th), New Haven and West Haven (116th), and Darien and Stamford (147th)—all for seats currently held by Democrats.

Democrat incumbent Elizabeth Esty is not seeking a fourth term in Congress, setting up primaries for both parties in the 5th U.S. House District, which stretches from Meriden and New Britain west to Danbury and the Litchfield Hills.
Former Simsbury first selectman Mary Glassman narrowly won the Democratic endorsement for the seat and faces Waterbury high school teacher Jahana Hayes in the party primary.
