Christie's in an awkward position. I really don't think he fits the Democrat ideology. But he is also realizing just how utterly dysfunctional the current Republican party is.
I think that pretty much summarizes the position moderate Republicans are in right now.
- Your party is far gone.
- You can't switch to Dem because the ideology doesn't completely match
- Even if you did switch to Dem, the Dems are so weak in your state/area that you can't get anything done
- Even if you have a stronger Dem support, it's like herding cats
- Third party is useless because you can't get through the primaries.
And nobody wants to be the frontrunner of another Republican party splinter.
