Mike McGuire is preparing to walk away from his job as a Sonoma County supervisor and run for the state Legislature, a move that would trigger a political shake-up in the north county.
Freshman Santa Rosa City Councilwoman Erin Carlstrom beat him to the starting line Tuesday, announcing her entrance into the race to succeed North Coast state Sen. Noreen Evans.
McGuire, who declined to confirm his plans, has notified supporters that he intends to run for the 2nd District seat that Evans will vacate next year.
The moves are a jolt to the state Senate race, which had already attracted two candidates from opposite ends of the sprawling district, stretching from the Golden Gate to the Oregon border.
McGuire, 34, a former Healdsburg mayor and school board member, would be an immediate frontrunner in the current field, some political observers said. They cited his name recognition, support among a cross section of political camps and substantial campaign coffers.
"He has the ability to leap in and really make a splash," said Sonoma State University political scientist David McCuan.
Several people notified of McGuire's decision last week said they expected an announcement soon on his bid for the Senate seat.
"That's the word I got," said Herman Hernandez, a Guerneville real estate broker who said he'd been told of McGuire's plans by Jason Liles, one of the supervisor's main political advisors and his appointee to the county Planning Commission.
In an interview, McGuire said only that he was "having conversations with supporters and folks throughout the (Senate) district about this issue."
"I will make an announcement at the appropriate time," he said.
