Musk chooses who he gives money to. He’s not going to give money to Bernie, who’s currently rallying against oligarchs. Instead, he’s going to give it to the people who are willing to push his fascist agenda. In the last election that was conservatives, but it’s not like the liberals don’t have freaks of their own. Money and advertising spend largely determines election outcomes, so by giving cash to politicians he likes, he can literally buy elections. Very few politicians would turn down his cash if offered, because they want the advantage it would bring. They also just have a fetish for sucking the toes of large donors.
