Polls open in Connecticut

Voters head to the polls in Connecticut

Polls opened at 6 a.m. Tuesday in Connecticut as voters cast their ballots in the state's primary election. The primary will determine the Democratic and Republican nominees for governor, U.S. Senate, and other state offices.

The most closely watched race is the Democratic primary for governor. Incumbent Gov. Ned Lamont is facing a challenge from two lesser-known candidates: former state Rep. Jahana Hayes and businessman Peter Lumaj.

Lamont is the favorite in the race, but Hayes and Lumaj have both campaigned hard and could pose a challenge.

Other key races to watch

In the Republican primary for governor, former state Sen. Themis Klarides is facing a challenge from businessman Bob Stefanowski. Klarides is the favorite in the race, but Stefanowski has campaigned hard and could pose a challenge.

In the U.S. Senate race, incumbent Sen. Richard Blumenthal is facing a challenge from Republican Leora Levy. Blumenthal is the favorite in the race, but Levy has campaigned hard and could pose a challenge.

Polls will close at 8 p.m. Tuesday. The results of the primary will be announced later that night.
