well for a group like AIPAC, most of their millions actually end up going to pro-Israel Democrats during the primary season. Apparently crypto and AI are also surprisingly big supporters of Dems this season, although this is likely just monied interests trying to build new puppets. Those groups are also spending in the millions.

It is likely that more money will end up spent on Republican campaigns than Democrat ones; having the world's wealthiest man-baby putting his thumb on the scale will just kinda do that. but it's predicted that this midterm election will end up having a total price tag over ten billion dollars. Those billions are coming with strings attached, for both parties.
