What you call someone who's been found guilty by a jury of the least serious of a number of charges against them and had the most serious charges end in mistrial after one juror refuses to convict. Blagojevicts and their attorneys often mistakenly and vociferously equate "hung jury" or "mistrial" with "not guilty." In general the more tenuous the jury poll to acquit, for example 11-1 guilty, the louder the Blagojevict and his attorney(s) scream that he was found innocent.
I would like to claim credit for coming up with this term, but a Google search revealed one earlier instance of its usage, in a comment on Huffington Post two years ago.
