Pete's gone native, that's why he's got a primary challenger.

I understand the 2nd phrase, but not the first. What is "going native"?

It means to take on the spots of the leopard you’re running with, or the chacteristics of the jungle, or neighborhood. As in Rome, do as the Romans do.

In congress, it’s do as the Rinos do.
