Last Monday, Fox News again turned to paid contributor Sarah Palin for analysis of a Republican primary debate. And once again Fox News hyped her potential run for the nomination.

On the Record host Greta Van Susteren prefaced her question with, “You have not announced your candidacy. You've given us no hint either way. And we keep all pounding on you and trying to pry it out of you with all sorts of sneaky questions.” And she did not hold back in any of her “sneaky questions,” such as: “So, where do you stand tonight?”; “Are you more interested or less interested -- more engaged in this, tempted, or just finished with it -- or what is it?”; and “How about a drop-dead date?”

Palin continued to play her part as well, keeping the mystery alive: “I'm still thinking about it, praying about it, contemplating, talking to my family.”

How long will Fox News keep Palin on payroll while she and her network hype her potential presidential campaign?

So who's winning the Fox Primary? Each week at Media Matters, we watch the interviews, crunch the numbers, and tell you what Fox is up to in the presidential campaign.

Methodology

Media Matters searched the Nexis database for all guest appearances on Fox News Channel, Fox Business Network, and Fox News Sunday for the 13 declared and potential presidential candidates in question: Michele Bachmann, Herman Cain, Newt Gingrich, Rudy Giuliani, Jon Huntsman, Gary Johnson, Thad McCotter, Sarah Palin, Ron Paul, Rick Perry, Buddy Roemer, Mitt Romney, Rick Santorum.

For programs where a transcript was unavailable, Media Matters reviewed the raw video.

Changes to the reports

Media Matters added McCotter to the data beginning on June 20 and Roemer beginning on July 21.

We stopped including Pawlenty and Trump in the data beginning on August 14; Pawlenty dropped out of the race on that date. And while Trump stated that he would no longer seek the Republican nomination but may instead run as an independent (on June 1, the beginning of this report), we decided to drop him from the data on this date.

We stopped including Bolton in the data beginning on September 6; Bolton decided not to run on this date.

*Correction: We have dropped all DeMint data from the report. During Laura Ingraham's June 14 show, DeMint told the conservative talk radio host that he is “not considering” a run for president in 2012. Media Matters regrets the error.
