Almost everyone can find something to agree with in Johnson's platform, plus he and his VP pick have experience. Stein and Baraka have never held public office before and only appeal to Berniebros.
Nitpick: "Berniebros" isn't the right word for Stein's fan base. She appeals to the usual progressives who normally vote for the Green Party, with an added bonus this time of delusional Sanders fans (I hesitate to say "Berniebros" because that seems to imply sexism), and a subtraction of those progressives who are just incredibly afraid of Trump.
Other than that, you're basically right.
No idea how "Berniebro" can sound sexist when it references their behavior but then again. SJWs man, SJWs -_-
