Elon Musk is reported to have given million-dollar checks to two Wisconsin voters, in a giveaway which (at least, as initially offered) required people to vote in the Wisconsin State Supreme Court election in order to be eligible to win.
According to Wisconsin statute 12.11, anyone who
Offers, gives, lends or promises to give or lend [...] anything of value [...] to, or for, any elector, or to or for any other person, in order to induce any elector to: [...]
- Vote or refrain from voting.
is in violation of the statute. To me, this seems quite straightforward: Musk's original (now-deleted) tweet reportedly offered million-dollar checks on the condition of voting. Even if Musk argues that the giveaway was actually made on a different condition as expressed in his later tweet, the original tweet makes an offer which itself seems to fall afoul of the statute, whether or not the offer is fulfilled.
However, according to the Guardian, a challenge by the State Attorney General was unanimously rejected by the Wisconsin State Supreme Court after also being rejected by two lower courts.
What is the legal basis for this challenge being rejected by the three courts?
