I think they are skirting it. Visiting the site and interacting with it the intended way will DEFINITELY put one's personal information into someone's hands but the question is, are they doing so deceptively as far as US law is concerned? Depends on whether the sender is apparently impersonating an entoty, whether "status as a ... voter" is a reserved government phrase and whether this qualifies as election misinformation. I'd guess probably not for all, so this text may very well be legal. And if the FTC/FTC cared enough, unsolicited political/commercial texts would have all been illegal regardless of any further malicious intent.
