Lieutenant Gov. Michael Fedele is expected to announced Monday morning at 10:30 a.m. that Danbury Mayor Mark Boughton will join him as his running mate.

Boughton himself had been vying for the gubernatorial nomination. He was polling around 4 percent, the same as Fedele, according to the March Quinnipiac University poll on the race.

The latest Rasmussen Report poll in early May has Fedele trailing Democrats Ned Lamont by 20 percent and Dannel Malloy by 17 percent.

“Fedele has consistently run not quite as strongly as Foley,” Rasmussen said in its press release on the poll.“His high point to date was 38 percent support against Lamont last month. This month’s findings are new lows for Fedele.”

Fedele’s announcement, according to sources, is expected to bring delegate support to Fedele six days before the Republican nominating convention. Fedele is still polling behind frontrunner, Tom Foley.

Boughton was elected mayor in 2001. Prior to that he served in the state legislature, representing the 138th District.

He graduated Danbury High School in 1982 and was a teacher at the school. He has a bachelor’s degree from Central Connecticut State University and a master’s degree from Western Connecticut State University.

Foley, a former Ambassador to Ireland and Greenwich resident, Larry DeNardis, former congressman, R. Nelson “Oz” Griebel, and C. Duffy Acevedo will be competing against Fedele for the nomination. Shelton Mayor Mark Lauretti also intends to petition his way onto the Republican ballot. And Chester First Selectman Tom Marsh, who was running as a Republican, will run with the Independent Party.
