“Trump is certainly a mine field for Republican governors who didn't back him to navigate,” said Rob Gray, a Massachusetts-based strategist who has advised Baker.

“If you are a bipartisan, moderate Republican governor in a blue state, Trump’s daily action or tweets can suddenly become a political spear that you have to dodge and divert attention from your agenda or the state political issues you’d rather be talking about

"You're lacking a seminal national issue that rallies energy toward the Republican candidate like Obamacare did in 2010," said GOP strategist Rob Gray, who is unaffiliated in the race.

Rob Gray: "Massachusetts is a majority independent state, with 53 percent of voters not enrolled in either party.

Brown tapped into that dynamic in the 2010 special election. At that time, he was seen as a regular guy, and his personality and the lack of a strong campaign by his opponent allowed him to eke out a win."

"Romney’s motivation, I suspect, is that losing twice still stings, so achieving a prominent position like secretary of state would wash away some of the bitterness of losing two presidential elections,” said Rob Gray, who served as a key adviser during Romney’s Massachusetts gubernatorial campaign and governorship.

If not addressed soon, the effects will be felt in the future, according to Kate Kahn, a spokeswoman from the Gray Media Group working with the MSCA.

Kahn said that by 2030, a quarter of the state's population will be age 65 and older.

"You've got a population that's increasing. It's the fastest-growing population in the state," she said. "You have need that's growing faster and faster."

A Baker spokesman dismissed the complaints.

“Looks like Christy Mihos is back negatively attacking Republicans again,” Baker spokesman Andrew Goodrich said.

“Christy’s negative campaign is one reason elected Republican officials from across the state are flocking to support Charlie Baker and see Charlie as our only hope to defeat Deval Patrick.”
