Ned Lamont announced on Twitter Wednesday morning that he is entering the race for governor of Connecticut in 2018.
In 2010, the 64-year-old Lamont ran for governor, losing to now-Gov. Dannel Malloy in the Democratic primary.
Malloy has announced that he is not running for re-election and several people have stepped forward since that announcement, saying they are running or forming exploratory committees to consider running.
In 2006, Lamont ran for the United States Senate. He defeated former U.S. Senator Joe Lieberman in the primary, but lost to Lieberman, who then ran as an independent.
Lamont is the founder of Lamont Digital Systems, which provides cable TV service to college students.
