The Democratic Senatorial Campaign Committee outraised its Republican counterpart by almost $300,000 in July, according to fundraising reports due to be filed with the Federal Election Commission on Friday.

The DSCC raised $4.4 million in July, making it the third consecutive month Senate Democrats’ campaign arm has outraised the National Republican Senatorial Committee. Democrats also ended July with a small cash-on-hand lead of almost $1.4 million.

“Even though Republicans have enjoyed a hospitable political environment, Democrats continue to outraise them and hold a cash-on-hand advantage,” DSCC National Press Secretary Deirdre Murphy said in a release. “The committee and candidates are all in strong positions to wage competitive races in each of our targeted races, including many red seats.”

The NRSC took in $4.16 million in July and now has $21.2 million on hand. The last time the NRSC outraised the DSCC in a month was April, but the committee remains optimistic about its fall prospects.

“The NRSC is well-positioned to help ensure that our candidates have the resources to win in November,” NRSC Executive Director Rob Jesmer said in a release. “Republicans are now on offense in at least 12 Democrat-held Senate seats and the wind is at our backs moving towards November as more Americans stand up and demand checks-and-balances in Washington.”

Of the 37 Senate seats up for election in November, CQ-Roll Call considers 13 to be tossups. Eight of those seats are currently held by Democrats; Republicans hold the other five. Independent expenditure spending by the campaign committees will be especially helpful in these competitive races.
