The problem with that is that free expression, including of political views, is explicitly protected. Elon Musk can use any amount of his own money and his own social media platform to express any opinion and advocate for any candidate or political cause short of literal “hate speech” which explicitly advocates for or directs criminal acts, and it is protected by that fundamental principle. And I don’t think we want to go down the road of carving out particular exceptions broad enough to cover anything that could be considered political advocacy because of the manifest impact that would have upon all other manner of free expression. “How do we stop someone like Elon Musk from using his wealth to promote a favored candidate?” is the wrong question; the better question is, “How do we prevent individuals from having a grossly outsized impact upon public and political opinions by dint of their massive wealth?”, and implicitly underneath that is, “How do we keep people from attaining such massive ‘wealth’ through market speculation and manipulation?”
Elon Musk isn’t just a “wealthy person”; he is the single most wealthy person in the world by a wide margin.. He has ‘acquired’ most of that wealth through grossly overvalued market speculation, and also used the influence of buying a barely regulated social media platform to espouse hateful and anti-democratic sentiments and to promulgate mistruths, conspiranoia, and outright lies. His actual “one vote” is meaningless in the scope of things, but his ability to credibly threaten legislators of the dominant party with being ‘primaried’ if they don’t support his ill-informed views and follow his dictums is as anti-democratic as it is perfectly legal. Musk has gone well past just promoting ideas or trying to persuade the public of his personal views; he is literally bypassing democratic processes to directly bully legislators, and regardless of how much you might think that elections are a marketplace of ideas where the best policy rises to the top, the reality is that the victor is generally the candidate with the biggest war chest and the most PAC money on their side. (And no, I don’t want to hear about how that is disproven by the massive disparity in the recent presidential election where Harris outspent Trump by a wide margin, because Trump basically didn’t even campaign and still managed to clear a solid margin in the popular vote, so that is obviously a massive anomaly.)
Elon Musk, a man who has never held public office, never really been a political figure or pundit of any kind prior to 2020, who is not any kind of expert or even essentially knowledgable about economics, foreign affairs, domestic policy, or anything else that would make him a credible participant in high level politics, now essentially has the ear of the President-Elect, plenary power to make decisions about how to make government “more efficient” (by which he apparently means cutting US$2T out of the approximately US$1.7T of discretionary spending in the US budget, so figure the math on that one), and now a stranglehold over the political party that has control over both houses of the federal legislature and a large plurality of statehouse legislatures and governorships. He should go for a trifecta and buy himself a Supreme Court justice or three, since they seem to be so cheap to rent. I think Kavanaugh and maybe Gorsuch are most his speed but maybe he can pick up Alito or Barrett for a premium, or just get a clear majority by clearing Roberts (who used to at least pretend to care about the reputation of the Supreme Court but now seems to be just fine diving head first in autocracy).
And unlike the billionaires and cabals of wealthy industrial interests hiding behind 527 orgs, Musk is doing it right out in the open with no sense of shame or notional restraint of ethics. He holds the power that no collection of individual citizens could ever exercise over sitting legislatures, and he is doing it to enact ‘policies’ and disrupt governance even before his political benefactor has any actual control. All of this, of course, is to establish control prior to January 20 so that the Heritage foundation fucktards and political operators can get in on the ground floor and implement as much of the Project 2025 directives as quickly as possible before a mercurial Trump can turn it all into churn or realize how little power he actually wields. That this is not stunningly obvious leads me to the observation that not enough people have read about events in Germany in the 1930-1933 timeframe and how an unpopular, obstructionist political party with a buffoonish but somehow charismatic leader backed by a group of leading industrialists managed to take complete control over the government and literally eliminate all political opposition.
