The easy answer is, money. Lots of it. With the deregulation of financial crimes (let’s see how badly the IRS gets gutted now), it doesn’t matter where the money comes from. But it will be necessary to invest heavily in the next midterm and presidential election to ensure JD Vance doesn’t automatically win.
Voting third party is fine. Protest voting is acceptable, though this result still fucking sucks. Strategic voting doesn’t have to be the default choice.
Anybody that did NOT vote, thinking it would be any sort of protest, is completely idiotic. Self imposed disenfranchisement only forfeits your own ability to say anything about the results.
