To Ceasar Cantu, President Obama is something like a hero. 

According to a press release from the White House, the president commuted Cantu's prison sentence, preventing the Texas man from serving nearly four additional years in prison than he should've. In 2006, Cantu pleaded guilty to marijuana trafficking and money laundering charges, but his offense level was incorrectly recorded as a 36 instead of a 34, which yields a 15-year prison sentence as opposed to the 11 and a half years he was supposed to serve. 

Though a judge decided that Cantu didn't catch the mistake early enough to do anything about it, President Obama swooped in with the clutch commutation, correcting a mistake that would've seized another three and a half years of Cantu's life.

Good save, Barry.
