The National Republican Senatorial Committee raised $4.2 million last month, making it the committee’s best off-year January haul since 2005.
The committee ended the month with $9.8 million in the bank, according to data obtained by Roll Call.
Republicans are largely on offense this cycle, looking to pick off Democratic senators who are up for re-election in states that President Donald Trump won last fall.
By comparison, the NRSC raised only $3.8 million during the first month of last year, an “on-year” because of the 2016 elections. The party went on to hold most of its seats last fall, with Democrats defeating only two GOP incumbents.
During the previous off-year, the NRSC brought in $2.4 million in January, ending the first month of 2015 with $4 million cash on hand.
Online donations ticked up this January from the same point in the previous two years. Ninety-nine percent of those donations came from grass-roots donors who gave $250 or less.
The Democratic Senatorial Campaign Committee has not yet released its fundraising numbers for the month. Committee fundraising reports are not always indicative of electoral success, especially since committee spending represents an increasingly small percentage of the vast amounts of money poured into competitive congressional races.
