The Democratic Senatorial Campaign Committee raised $5.1 million for November, an off-year November record for the committee.
The DSCC now has more than $12 million cash on hand and has paid its debt down to $5 million, down from $6.2 million a month ago.
It kept up its strong fundraising pace despite a rough month for Democrats stemming from ObamaCare's rocky rollout. The month was also truncated by Thanksgiving, traditionally a tough week to fundraise.
"The reckless and irresponsible Republican agenda remains wildly unpopular and Democrats across the country are energized," DSCC Executive Director Guy Cecil said in a statement. "The Koch brothers are aggressively blanketing the airwaves in a few key battleground races, but we are raising the resources to fight back. We are incredibly thankful for our supporters who time and again have stepped up to protect a Democratic majority in the Senate."
