A party requires base beliefs. It builds of of those beliefs. Its survival requires popular support, and in this age of electronic communication, a lot of money. The money allows the party to get its message out to the masses.
The GOP message is this; we believe in the intellectual superiority of the white race. This has proved to be a disaster in a country evolving into predominantly non white majority. I have listened to the GOP leadership espouse their understanding of its party's problem. Not unexpectedly the white superiors have already identified the fix! The intellectually superior white party is going to implement changes that will embrace the concerns of the inferior non white majority! How can the mentally inferior non white majority reject our benevolence!
If the GOP party doesn't remove the leaders that believe the white supremacist dogma, it will continue toward its inevitable extinction. The money is not stupid, just the party. Money aimed at a shrinking base is a lunacy that will not be allowed to continue much longer!
