He was initially the frontrunner for the party's nomination, as he had more name recognition and financial means than his opponents and had lived in three of the towns in the district (Cohasset, Weymouth and Scituate).

During his tenure on the Authority, Mihos frequently clashed with Chairman Matt Amorello over a number of issues regarding the Big Dig's budget and excessive spending.

Mihos sued claiming that the governor did not have the authority to fire them, and it was eventually brought before the Massachusetts Supreme Judicial Court.

[6] Mihos later sued Governor Swift for violating his First Amendment right to free speech and settled that case in U.S. District Court for $197,000.

In 2004, when Mihos's five-year term on the authority expired, Governor Mitt Romney replaced him with Daniel A. Grabauskas, the 2002 Republican nominee for State Treasurer.

[8] An article published on March 21 in The Boston Globe drew attention to Mihos's interactions with public university professor Lou DiNatale.

"[9] On June 8, Mihos announced that he had chosen John J. Sullivan, a Winchester, Massachusetts town moderator and lifelong Democrat, to be his running mate.

[10] In September, Mihos generated controversy by airing an animated political commercial,[11] which showed a Big Dig engineer and politicians with their heads literally up their behinds.

In the November 7 general election, Mihos only garnered approximately 7% of the vote, with Healy at 35% and Democratic candidate Deval Patrick at nearly 56%.

[4] On February 21, 2012, Andrea Mihos went to the Yarmouth, Massachusetts, police station to report an alleged domestic assault the previous evening in Stuart, Florida.

She told police she was concerned for her husband's mental health, as his behavior had become increasingly erratic and aggressive due to political and business setbacks.

According to the police report, the assault occurred during an argument in which she reminded her husband of his bad behavior, including hiring prostitutes, strippers, and porn stars for sex.

[20] On June 27, 2012, Mihos was charged with assault and battery for an incident that occurred between him and his wife in July 2011 at their home in West Yarmouth, Massachusetts.

[21] In April 2014, he reached an agreement with prosecutors in which the charges would be dropped if he successfully completed nine months of pretrial probation, refrained from contacting Andrea Mihos except through e-mail or their attorneys, completed a mental health evaluation and underwent any necessary treatment, and refrain from publicly commenting on the case unless with Andrea Mihos and/or her attorney.
