A conservative super PAC is marking the Thanksgiving holiday by releasing a two-minute ad that relentlessly attacks President Obama's record.

The Conservative War Chest ad, released Wednesday, is designed to help Rep. Bill Cassidy (R-La.), the front-runner against Sen. Mary Landrieu (D-La.) in next month's U.S. Senate runoff. But there is no mention of Cassidy until his name flashes onscreen at the very end.

Before that, it's all Obama, all the time.

"What if they held an election, but America's president said it didn't count?" asks the narrator. From there, he asks a series of other "What if" questions that serve as implicit criticisms of Obama for taking executive action to halt the deportations of millions of undocumented immigrants and reaching a climate accord with China, among other things.

The commercial also accused the media of "stopping their own reporters from talking about a chief executive who doesn't think he is accountable."

It concludes: "Wouldn't all that mean that this Thanksgiving, as we gather together and give thanks for a country founded on a principle that no one is above the law and our leaders answer to us and not the other way around and that a free press protects our freedom, that we should also say a prayer that it will always be so?"

It's not clear how much money the group is spending on the ad. A spokesman, Mike Flynn, said in a statement that "We are pleased to have time on NFL football on Thanksgiving Day as well as local news over the weekend."

The ad is part of the GOP strategy in the Louisiana runoff to fuel support for Cassidy by casting him as a candidate who will stand up to the president in Washington.

Landrieu's campaign and her allies are pitching her as the candidate who has voters' backs.

Polls leading up to the Nov. 4 all-party primary showed Cassidy favored in a runoff against Landrieu. The runoff is Dec. 6.

The White House press office did not immediately respond to a request for comment on the ad.
