Washington (CNN) - Call it the New York-23 effect: Both the Democratic and Republican congressional re-election committees spent more money than they took in last month.
The Democratic Congressional Campaign Committee reported Thursday that it raised $3.76 million in October, but spent $3.98 million. A similar story from the National Republican Congressional Committee, which said it brought in $3.4 million last month, but spent $3.6 million.
So where did the money go? Both committees infused campaign cash into the special election in New York's 23rd congressional district.
The race, to fill the seat left vacant when Republican congressman John McHugh stepped down to become Secretary of the Army, turned into a three-way contest between official GOP candidate Dede Scozzafava, Conservative Party candidate Dough Hoffman, and Democrat Bill Owens.
Scozzafava dropped out of contest three days before the election, after conservatives in the GOP backed Hoffman's bid. Owens ended up narrowly winning the election, taking a district Democrats haven't controlled since the 19th century. A count of absentee ballots continues.
The DCCC says it has $14.52 million cash on hand, with $3.3 million in debt. The NRSC reports $4.2 million in the bank, with $2 million in debt.
Next November, all 435 seats in the House of Representatives are up for grabs. Democrats currently hold a 258-177 advantage in the House.
