N.H. jury acquits consultant behind AI robocalls mimicking Biden on all charges

… Kramer, who owns a firm specializing in get-out-the-vote projects, argued that the primary was a meaningless straw poll unsanctioned by the DNC, and therefore the state’s voter suppression law didn’t apply. The defense also said he didn’t impersonate a candidate because the message didn’t include Biden’s name, and Biden wasn’t a declared candidate in the primary.

Jurors apparently agreed, acquitting him of 11 felony voter suppression charges, each punishable by up to seven years in prison. The 11 candidate impersonation charges each carried a maximum sentence of a year in jail.
