If I were the judge, I'd probably give him a break. But I don't know the specifics or the sentencing guidelines here. I was just thinking up the maximum possible sentence that I wouldn't think of as outrageous beyond all reason.
He was convicted of a misdemeanor for the substantive offense and then got hit with felony obstruction of justice for wiping his hard drive, which obviously didn't work.
He's basically an idiot kid that managed to gain access to an idiot politician's email by guessing the answers to her security questions using publicly available information. To even call him a "hacker" is to denigrate real hackers everywhere.
