While she nearly matched him in fundraising for the corner, Democratic challenger Sara Orozco headed into the final weeks leading up to Election Day at a large financial disadvantage to incumbent state Sen. Scott Brown, according to their filings with the Office of Campaign and Political Finance.

Brown, a Wrentham Republican, raised $38,620 from the end of August to Oct. 17, finishing the period with more than $96,500 in his campaign bank account.

Orozco, of Needham, raised nearly $36,600 during the same period, but finished with $10,260 in her campaign coffer.

Both candidates relied primarily on contributions from individuals. Brown also took in $500 from the Massachusetts Correction Officer Federated PAC and the MBTA Police Association PAC.

Orozco received $500 from the Democratic State Committee and also received a $150 contribution from Attorney General Martha Coakley. The Progressive Massachusetts PAC also chipped in $200.

Brown also outspent Orozco. Brown doled out nearly $52,000 during the period while Orozco spent nearly $35,000.

Brown paid nearly $25,000 to the Massachusetts Republican State Committee for "mailers and support" while his other expenditures were for typical campaign related materials.

Orozco doled out $1,250 to 3-Street Inc., a Cambridge consulting company, and $3,200 to Dan Cohen's polling shop, Connection Strategies.
