US Senate candidate Elizabeth Warren received more in campaign donations from Boston in the first three months of the year than from any other city in America, collecting more than $374,000 from residents of the state capital, according to a Globe analysis of campaign finance documents.
Warren, a Democrat who has been criticized by Republicans for raising most of her massive war chest from out of state, collected $1.7 million in large contributions from Massachusetts residents in the first quarter this year, the most from any state. She received $479,000 from New York residents and $426,000 from Californians, who ranked second and third in support for her campaign.
The consumer advocate and Harvard Law School professor outraised her potential Republican opponent, Senator Scott Brown, among large donors in the Bay State in the first three months of 2012, with Brown collecting $1.3 million in itemized donations from Massachusetts residents in the first quarter. He raised $214,000 from Florida residents and $191,000 from New Yorkers.
The rankings include only contributions of at least $200, for which the Federal Election Commission requires candidates to include the address and occupation of donors. Smaller contributions may be reported as one lump sum, with no details on the donors.
Warren raised $6.9 million during the first three months of the year, a massive sum that doubled the $3.4 million raised by Brown. The Warren campaign has said that about $2.5 million, or 36 percent, of its total money raised in the first quarter, including the smaller donations, came from Bay State residents.
With about $15 million in his campaign account by March 31, Brown still leads Warren in total cash. Warren reported about $10.9 million in her account on March 31.
The candidates are expected to spend “in excess of $20 million each,’’ said Stuart Rothenberg, editor of the Rothenberg Political Report, which follows political races on a nonpartisan basis. “That is the top of the top tier’’ among expensive races, he said.
The Massachusetts contest, which Rothenberg currently rates as a toss-up, combines several elements that drive up costs, including the fact that Massachusetts is a populous state with an expensive primary media market, in Boston, as well as several secondary markets, he said. Also, the race features candidates who are accomplished fund-raisers with national appeal, and the election is taking place in a year in which political control of the US Senate may come down to one race, said Rothenberg.
“That is a prescription for a lot of money,’’ he said.
Though candidates reported their fund-raising totals last month, the data was not immediately available from the Federal Election Commission in electronic form that can be easily analyzed. The Federal Election Commission released Brown’s report in a form that could be downloaded and analyzed earlier this month. An analysis showed that he raised more in itemized contributions from New York, $141,520, than any other city. He received $138,640 from Boston.
Only on Monday did the election commission released Warren’s campaign report in a comparable form. After Boston, Warren’s next-highest total among cities was the $303,043 she collected from New York. Cambridge was third on her list, with $264,154 in contributions, then Newton, with $173,960, and Washington, $139,207.
Rounding out Warren’s top 10 cities are Brookline ($100,113), Philadelphia ($77,070), Dallas ($75,795), Wellesley ($55,265), and Austin, Texas ($49,727).
Warren reported raising about $165,000, or 2.4 percent of her total, from political action committees, including contributions from PACs controlled by unions, such as the Teamsters, and unions representing autoworkers, steelworkers, bricklayers, and schoolteachers. She reported contributions from the Planned Parenthood Action Fund PAC, as well as leadership PACs controlled by members of Congress, such as US Senator Daniel Inouye, a Democrat from Hawaii, and Senate majority leader Harry Reid of Nevada.
Brown raised $394,000 from political action committees during the first quarter, about 11.7 percent of his total.
