Both were long-shots to get the nomination, as Christie was a notch too moderate (despite his in-your-face persona) to get nominated and Fiorina seemed to fail to find a niche; she was well-liked but was few people's first choice.
We have some folks antsy to get the winnowing process over with quickly and have a one no-Trump bid. That's what we're working on. Iowa serves as a theocon screener and New Hampshire serves as an establishment screener. NH didn't quite do its job, leaving three folks in the center-left track rather than one or two. Bush did well enough to not pack it in quite yet and Kasich's second place showing will likely let him fight on until Michigan votes in March.
