With just days to go before Boston’s mayoral election, mystery money is flooding the race, most of it going to benefit Marty Walsh.

CommonWealth’s Paul McMorrow called it “dark money” in a report last week that documented how funds raised by shadowy outside PACs were flowing into Boston to help elect Walsh. The money is dark because the donors won’t be identified until long after the election and their donations are not subject to standard campaign spending limits.

McMorrow reported last week that spending by the outside groups on a per capita basis far exceeds anything seen nationally, even in big-city mayoral races in New York and Los Angeles. David Bernstein, writing in Boston magazine, asks whether the Boston mayoral race is for sale.

The pace of outside spending in the Boston race seems to be accelerating in the final days before the election. The Globe reports that a newly formed group called One Boston is pumping $480,000 into television advertising on behalf of Walsh. One Boston is headed by a 55-year-old Roslindale woman who has not voted in three of the last four municipal elections. The group’s donors won’t be identified until January.

The other group muscling its way into the Boston mayoral election is called American Working Families. The group, which is spending $1.1 million on behalf of Walsh, lists as its address a UPS store in Virginia. The only name associated with the group is Bud Jackson, a Democratic media consultant.

On Twitter, McMorrow offers a nifty chart showing the impact of the outside spending on the race. The Globe reports that outside groups have independently spent $2.4 million on behalf of Walsh, whose campaign had raised and spent only $1.7 million through Oct. 15. Two education groups that have been active in Massachusetts politics in previous years have spent $713,000 supporting Walsh’s rival, John Connolly.

Walsh tells the Globe and the Herald he knows nothing about the outside groups supporting him. The groups are barred by law from coordinating their activities with the campaign.

The state Office of Campaign and Political Finance urged the outside groups in September to identify their donors, but so far they have refused. Bernstein says he suspects most of the money backing Walsh is coming from union sources.
