Pro-Gingrich Super PAC Winning Our Future has released a new TV spot to air in Florida ahead of that state’s primary. It may be the harshest attack ad of the campaign so far:

Politico reports some $6 million is behind the ad campaign, meaning it could reach saturation levels in Florida’s (many) expensive media markets.

The buy comes in the wake of news yesterday that Sheldon Adelson, the Las Vegas billionaire who donated $5 million earlier this month to Winning Our Future, dumped another $5 million in via his wife to keep Newt ticking.
