Altschuler, a millionaire, spent $1.2 million in the Oct. 14-Nov. 22 period, according to the Federal Election Commission. Bishop, a former provost of Southampton College, spent $859,768. The largest expenditures were for advertising.
During the two-year election cycle, Altschuler spent $4.2 million compared with Bishop's $2.5 million. However, the Republican's total includes a $2.5 million outlay for a three-way primary contest.
The race is too close to call more than a month after Election Day, with Bishop holding a narrow lead over Altschuler.
Both candidates have made fundraising appeals to pay for lawyers overseeing the recount. Altschuler had $199,820 left in his campaign treasury as of Nov. 22; Bishop had $315,390.
Altschuler raised $1.5 million between Oct. 14 and Nov. 22, including $1.3 million from his personal bank account. Among the notable donors were cosmetics executive Ronald Lauder, who gave $2,400.
Bishop collected $357,239 in the period. His contributors included former Rep. Michael Forbes who once held the House seat and gave $1,500.
McCarthy raised $119,214 in the 40 days ended Nov. 22, spent $454,923 and had $192,845 left over. Becker, whose strong challenge of McCarthy surprised some political experts, had not filed his fundraising report as of Friday.
