HARTFORD, Conn. — State Comptroller Kevin Lembo is dropping his bid for the Democratic nomination for governor and will instead seek re-election to his current position.

The announcement Thursday eliminates one of the better known Democrats from a crowded field of candidates mulling a run for the nomination to succeed Democratic Gov. Dannel P. Malloy in the 2018 election. Malloy is not seeking re-election.

Lembo said in a statement that he wants to remain in place as “an independent government watchdog and advocate for essential fiscal and economic reform.”

Another well-known Democrat, Lt. Gov. Nancy Wyman, has not yet said whether she plans to run for governor.
