Republican state senator Toni Boucher is considering jumping into the governor's race.
Boucher, who represents the 26th Senatorial District, announced on Tuesday that she is forming an exploratory committee for governor.
"I think it's a great way to test the waters before spending a lot of financial resources to see if you can gain that kind of support," Boucher said.
State senate Republican leader John McKinney has announced plans and Tom Foley has yet to state what he plans to do.
In a primary, Foley tops the field with 36 percent, McKinney with 11 and Boughton with 8. Boucher was not polled.
Malloy has not yet said whether is will run for re-election.
