Connecticut Republicans have endorsed Southington state Sen. Joe Markley as the party's lieutenant governor candidate, but he faces a likely August primary.
Both New Britain Mayor Erin Stewart and Darien First Selectman Jayme Stevenson received enough support to qualify for the primary.
Markley has served two stints in the Connecticut General Assembly. The first was in 1984, when he served two years in the state Senate. Markley returned in 2010 and has been an outspoken fiscal conservative.
Stewart was a newcomer to the race. Formerly a gubernatorial candidate, she switched to lieutenant governor on Friday.
Democratic Lieutenant Governor Nancy Wyman is not running for re-election.
