Fox jumped on board the “Cain Train” this week, increasing the airtime it's giving to Herman Cain. The former Godfather's Pizza CEO's domination of the Murdoch media spread across more than one Fox network and included a 14-minute-long appearance on Fox Business' Imus In The Morning.

Cain appeared on Fox about three times as often as the next closest candidate.

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.

Softball Question(s) of the Week: From the October 4 episode of Fox and Friends, co-host Steve Doocy asked Herman Cain the following:

DOOCY: When you were in the green room, I gave you the news that you hadn't heard yet. There's a brand new Washington Post/ABC poll out that shows, look at this, you're now in second place. Rick Perry has - ties - you at sixteen percent, Mitt Romney at twenty-five. Perry's lost about half of his support, and it looks like, sir, it's gone to you?

Methodology

Media Matters searched the Nexis database for all guest appearances on Fox News Channel, Fox Business Network, and Fox News Sunday for the 12 declared and potential presidential candidates in question: Michele Bachmann, Herman Cain, Newt Gingrich, Rudy Giuliani, Jon Huntsman, Gary Johnson, 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 stopped including Palin in the data after her decision not to run was made on October 5. Giuliani announced on October 11 that he would not run, so he will not be included in future reports.

Media Matters added McCotter to the data beginning on June 20 and Roemer beginning on July 21. We stopped including McCotter on September 22; he dropped out of the race that day.

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.
