Trish Regan or a re-vamped Kennedy would have been a better choice.
Trish and Kennedy both are better than MacCallum. They have a bit more charisma and definitely are bolder when it comes to interviews.
Kennedy's full name btw is Lisa Kennedy Montgomery
Martha is fine, but I agree with others that her debate skills are lacking. She covered some of the Trump rallies and seemed to thoughourly enjoy sharing in the excitement.
Kennedy is a given. She will end up with a plum spot on Fox. Very quick witted, completely in tune with the Gen X/Millennial crowd but right now half of the Fox prime time demo wouldn’t have clue what she is talking about.
