It’s all part of the narrative. They got Rubio into 2nd place to start his ascent. The veil just slipped a little. that’s all. The polls are use to ebb and flow what they want the topics to be about. This was the slow ascent of Rubio, blah blah blah. And we know Fox is is biggest fan, so it makes sense.
I think you’ve pegged this. They’ve got Rubio second and Kasich fourth when it will probably be just the opposite. Fox News bias?
