I think that we can skip the middle layer wetware and just elect cash president. With the (multi) billion campaign season that comes - who is in charge will be just a formality.
Side note - how amazingly high ROI you got with donations to politicians - for a couple of hundred of million - you get people that oversee and direct the 3-4 trillion dollar federal budget (scale to state level too).
Can I send my cash to jury duty? :)
