John Haggerty was convicted in December 2011 of second-degree grand larceny and second-degree money laundering charges.
Haggerty was found guilty of stealing hundreds of thousands of dollars from Mayor Bloomberg that was supposed to go toward an Election Day poll watching operation.
The political operative instead used the money to buy a house.
Prior to his court appearance Tuesday, Haggerty had been out on bail pending an appeal.
He will spend at least 16 months behind bars and have to pay Bloomberg $750,000 in restitution.
Meanwhile the man who used Haggerty's Independence Party to launder money and skirt campaign finance laws - Mayor Michael Bloomberg - has not been held accountable at all for his crime.
Funny how that is.
