I think this is removing the "Christie" wing from the process, which would be an establishment wing to be sure.
Christie is not longer on the transition team, so anyone he may have wanted will be under scrutiny.
This isn't necessarily a bad thing, and I am sure there will be some "establishment" types that make the cut.
We are talking about 4,000 people here that need to be hired, and they won't all be "Trump Train" people, the odds are against it.
Christie's ship sailed when he embraced Obama on the beach, right before the 2012 election, and with his lukewarm Romney endorsement.
Then comes, Bridge-gate, which would have come up, had Trump named him as his VP pick, which was in the works for a while.
A "purge" of the unfaithful? No, I don't think so.
More of a "shaking up".
Making Pence the head of the transition team was a good move, over Christie.
I think Pence would help get people on board that would do the job, rather than as a patronage, as Christie would have.
