“Elon Musk is likely to end this election cycle as the biggest single donor. He’s also surprisingly hard to find,” the Washington Sun reports.“The last time Elon Musk got involved in an election, last year in Wisconsin, he was everywhere: He spent millions of dollars and danced onstage before a crowd of thousands wearing a block of foam cheese on his head.
