The National Republican Senatorial Committee outraised the Democratic Senatorial Campaign Committee in April, taking in $3.43 million to the DSCC’s $2.8 million.

The NRSC has now raised a total of $14.65 million through the first four months of the year, while the DSCC has raised $14.5 million. The two committees’ cycle-to-date totals were close through the end of March as well.

The DSCC now has $6 million on hand while carrying $4.3 million in debt. The NRSC has $1.38 million cash on hand after using half its April receipts to pay down debt. After starting the year with $6.5 million in debt and ending March owing $2.75 million, the committee chopped its debt down to just $1 million.

Thanks to the fact that more than twice as many Democratic incumbents are up for re-election this year, the Senate landscape remains slanted in the favor of Republicans. Making the cycle more challenging for the Democrats is the growing number of open seats. Wisconsin Sen. Herb Kohl last week became the sixth Democrat to announce his retirement.

“Given the expanding Senate map and the increasing number of Democrat retirements, including most recently in Wisconsin, it’s more important than ever for Senate Republicans to be on solid financial footing,” NRSC Executive Director Rob Jesmer said.
