If you look strictly at Mueller Team dynamics and optics, Mueller is the only one who has garnered both Left and Right respect and support.
He has the least to lose if he turns out to be /ourguy/. All the others on his Team are confirmed one-sided cabal Left-wing Demfucks.
Mueller is also a Marine, unlike the others including his little beta-fuck crony Comey.
I believe Mueller has the highest likelihood of being /ourguy/ and just like Trump wants nothing to do with his past connections with anything remotely Dem or Clinton-related, after what he has witnessed from 2016.
