Maybe DC elites have decided to back Ryan or Walker... since they’re not going to choose anyone who ran for President they might as well go with a favorite.
IMHO the elites want a reliable elite like Romney/Ryan, but they need a brokered to get the cutouts. All the other one contesting so far except maybe Jebula were merely to get votes away from Trump.
If Trump can get the 1237 the elites will have a very hard time stealing it.
