I agree. My wife and I were watching her press conference yesterday and we said the same thing - she's extremely intelligent, great poker face, the most prepared press secretary every with her alphabetical binder. Rarely is she flustered and surprised.
The only issue is that she is a living contradiction. She hated Trump and what he stood for before she got the job and now she probably has one of the worst professional roles in the world trying to clean up Trump's constantly bumbling and village idiot decisions. She comes across like she can't wait for this gig to be over, but I'm not sure what's next for her. She has stated her dream job is an anchor/show on Fox, but they are loaded at the moment with Tucker Carlson, Sean Hannity, and Ingraham and the Five.
Anyway, definitely a smart cookie and extremely dedicated and professional at her job. Hopefully she has enough work-life balance to work out a little as there is not a muscle on her body.
