Just like its counterpart in the House, the Democratic Senatorial Campaign Committee outraised its GOP equivalent in January, and both Senate committees ended last month carrying debt leftover from the 2008 election cycle.

According to fundraising numbers set to be filed with the Federal Election Commission on Friday, the DSCC had $10.9 million in debt at the end of January but also raised more than $2.5 million last month. The DSCC spent just less than a million dollars in January and will report about $1.9 million in cash on hand.

The National Republican Senatorial Committee is carrying much less debt, a little more than $4 million, but the GOP committee also raised less and spent more in January. The NRSC raised about $1.8 million last month, spent $1.5 million and reported just more than $1 million in cash on hand.

The DSCC and NRSC have made visible efforts to talk up their opportunities in 2010. After two good cycles for Democrats, DSCC Chairman Bob Menendez (N.J.) said in a press conference last week that the best defense in 2010 will be a good offense. And although Republicans have seen a rash of early retirements take place early this cycle, NRSC Chairman John Cornyn (Texas) has promised an aggressive strategy and pointed to places like Illinois, New York and Delaware as places where the party sees new opportunities.
