Dems outspent GOP 1.26 Billion to 890 million in their own campaign funds (31% more), with Dem PAC contributions on top of this dwarfing Republican by at least 2 to 1 (Mostly from the contributions of a handful of billionare Dems which is important to note since if this came from individual voters, it would have much greater voter implications wrt enthusiasm).
