Former Fox employees Rick Santorum and Newt Gingrich took the lion's share of last week's Fox Primary, with the two collectively appearing on Fox for over an hour and a half. Santorum and Gingrich accounted for over 50 percent of the time Fox devoted to interviewing the Republican presidential field.

Mitt Romney made just one appearance, but his presence was felt elsewhere on Fox, with host Eric Bolling declaring “we're all on board if Mitt's it,” while Sean Hannity warned off Gingrich and Rick Perry from attacking Romney's record at Bain Capital.

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 10 declared and potential presidential candidates in question: Michele Bachmann, Herman Cain, Newt Gingrich, Jon Huntsman, Gary Johnson, 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, 2011 and Roemer beginning on July 21, 2011. We stopped including McCotter on September 22, 2011; he dropped out of the race that day.

We stopped including Pawlenty and Trump in the data beginning on August 14, 2011; 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, 2011, 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, 2011; Bolton decided not to run on this date.

We stopped including Palin in the data after her decision not to run was made on October 5, 2011.

We stopped including Giuliani in the data after he announced on October 11, 2011 that he would not run.

We stopped including Cain in the data when he suspended his campaign on December 3, 2011.

We stopped including Johnson in the data on December 28, 2011; Johnson announced he would seek the Libertarian Party's nomination.

We stopped including Bachmann in the data when she suspended her campaign on January 4, 2012.
