The top super PAC supporting Newt Gingrich is going up with nearly $900,000 worth of radio ads in six key states holding contests in the next two weeks.

The Winning Our Future ad buy appears to come on the heels of another significant cash infusion from casino mogul Sheldon Adelson and gives Gingrich the kind of presence on the airwaves that he hasn’t had on Super Tuesday, which could be a make-or-break moment for his struggling campaign.

According to figures provided to The Fix by a media buyer, the super PAC bought $238,000 worth of ads in Georgia, $235,000 in Ohio, $172,000 in Tennessee and $98,000 in Oklahoma. It is also buying in two Southern states holding primaries a week later — $92,000 in Alabama and $32,000 in Mississippi.

The ads in the Super Tuesday states will run this week, while the ads in Alabama and Mississippi will run the week before their March 13 primaries.

Winning Our Future spokesman Rick Tyler said the ads come on top of a national radio buy the super PAC has launched.

The super PAC got a big boost in recent days when Adelson — who along with his wife had spent $11 million helping Gingrich — sent more money.

Gingrich skipped Tuesday’s contests in Arizona and Michigan, in large part because his campaign didn’t have the funds to compete with Mitt Romney and Rick Santorum.

It remains to be seen how much money the super PAC will have to play around with in the coming days.
