I keep saying these numbers are irrelevant as the GOP and Dem funding models are so different. The GOP accrues huge war chests, mostly to fight against conservatives or line the pockets of their consultant buddies. For example, the current mess in Virginia is due entirely to the GOP fighting against THEIR OWN CANDIDATE two elections ago, supporting instead Xlintoon bag man Terry McAwful and his successor, Gov. Baby Killer McGungrabber.
The Dems fund candidates more directly through decentralized support, i.e. individual/corporate/PAC commies send money to their favorite commie candidates directly. Plus, the Dems have the overwhelming advantage of controlling nearly the entirety of the media, and can thus count on $5-10 BILLION in friendly news coverage, $20B if you count down ballot elections.
That was pre-Trump and before dozens of RINOs were retired or were defeated over the past two election cycles. We're living in the era of Trump and Trump and his allies in the party are going to have the most control on how the GOP money is spent.
