I think Fiorina is likely an Ni ego, probably gamma NT and more likely rational.

Ben Carson is EII or LII. I could definitely see Fi-Ne, but i don't know for sure.

Hillary Clinton- LSI

Trump- SLE

Chris Christie- SLE or ESE

Bernie- probably is something like LII or LSI. Leaning LSI from what I've seen.

Rubio- idk? EIE?

Cruz- ESE or LSE, i think.
