I see you argument clearly. But there is the other side of the medal and that is how many INTJs are willing to go so public with their life and opinions ? Not many and almost certainly not the ones that are 5s. I personally think that she a 3 or 6. (on the second thought she is surely being fed with acting/saying the "correct" stuff but she often fails at this because she simply is not hardwired for this ... and then she comes as a fake. What suggests a 6 or parhaps even one very pragmatic 1 or 8w9)
Rubio is what he is becase he is completely stereotypical e3 person from what I see, what is required in America out of everybody that really really wants to be something (what is actually very Fe like behaviour). While real ENTJ may have quite a problem with all those ass kissing, since it is grosse and humiliating. One of the reasons why I was mistyped was because ENTJ profiles are so biased towards corporate America that for me as none American that made it really hard to relate to the ENTJ profiles (and I still don't for the large part). America is in so deep crisis right now exactly because it forgot what is good and good quality leadership and instead it prefers stereotypical e3 careerists that have a serious lack of knowledge how the world really works. Today you have a whole culture of people that want to be " the ENTJs" but even most of sucessful onces are obviously not. This type got so mixed with success that this made a caricature that basically no one can measure up to (except some really wealthy investors). Therefore she struggles in this regard but she must make certain groups happy if she wants to do something. ENTJ and especially eNTJ really isn't that much different than INTJ with the exception of how easy they find to engage the world ... and I see no major problems in that regard with her.
(but as I said I am not an expert on this woman)
