Fox News ran those debates in violation of FEC regulations.

(b) Debate structure. The structure of debates staged in accordance with this section and 11 CFR 114.4(f) is left to the discretion of the staging organizations(s), provided that:
(1) Such debates include at least two candidates; and
(2) The staging organization(s) does not structure the debates to promote or advance one candidate over another.
Wrong. Megyn asked tough questions of every candidate that hit directly on their vulnerable points. Trump is the only one who whined about it then and still months later.
Now, it’s really all a smokescreen and an excuse because Trump’s afraid to face Cruz, who he knows is loaded for bear and is the first candidate with the chops to take him on head to head on the stage and win.
