Between "The Devil's Chessboard" and Harvey O'Connor's "Empire of Oil"(1958), it's obvious that there's really only the Money party. All of the marketing schtick about rights is to distract from the apathy of politicians who really couldn't care less about a "more perfect union" because conflict sells shiny noisy crap (and the oil to make and power it).

"Consumers All" is the goal; not any particular usefulness of humanity to its future.

With all of the rhetoric flying around, there's no sensible reason for the 50/50 split between the candidates except that is how the money works out: half of the money goes to the party that will support corporate destruction, and the other half goes to a party promising to help poor people buy more stuff from the same corporations. Trump sells beer, trucks and guns and Harris sells gasoline to all the protesters driving to rallies against Trump.

Candidates are mostly adjacent to cashflows, and once elected, they are enslaved to those cashflows.
