Then there is a concept known as RINO Creep. That is , the definition of RINO may be currently changing to include those today who would not have been included earlier.
Arlen Spectre and Chuck Hagel are classic RINOS. But John Bolton? Probably not but he has been included in the black list because he came out for McCain.
It’s all ok however because tha primary process is designed to learn where the boundries are and determining the center within those boundries. One thing is pretty clear, the center has shifted and many are unhappy about that shift.
The general election is another matter. The question becomes “Will the center shift result in more coming within the boundries than those leaving the boundry?”
The answer is of course...... those around the center must work hard to prevent those on the fringe from fading away.
