Mainstream G.O.P. Field of Three Faces Brutal Delegate Math (Nate Cohn) from the New York Times
"On Super Tuesday, March 1, 25 percent of the delegates to the Republican national convention will be awarded. If the mainstream field hasn’t been narrowed by that point, it will become very hard to avoid serious damage to the candidate who ultimately emerges as the party’s anointed favorite. The top mainstream candidate could easily fall more than 100 delegates short of what he might have earned in a winnowed field. He would even be in danger of earning no delegates at all in several of the largest states because of one number: 20 percent."
