See an analysis for RealClearPolitics by Jeffrey H. Anderson of where the GOP nomination process now stands. He splits Republicans into four groups - The Trumpers, The Cruzers, The Realists, and The Ostriches - and identifies well-known members of each group.
Anderson does a particularly effective job of describing the role of John Kasich in this process. He questions Katich's motives in remaining in the race, seeing at least two possibilities: one nefarious, the other naive.
This column is relatively even-handed between Trump and Cruz, unusual punditry in these troubling times.
