Pretty much. Same thing happened in 2018. RNC far out raised DNC only for a mountain of money to pour into the coffers of Democratic candidates from billionaires like Soros and Bloomberg. They ended up taking The House. If I were The RNC I wouldn't crow too much but rather quadruple efforts to raise money.
Most campaign money is raised by the candidates, and some of the Democrats substantially outspend their Republican opponents in close races. I dont think the reverse has happened in recent years.
