She was part of a delegation of about a dozen members of congress including a couple republicans.
She’s a politician who has higher aspersions. She’s not really unique in that sense. She’s not a “chosen” candidate. She has been angling to run for governor for years.
Speaking at Davos was just an opportunity for her to build her brand. She was on the same panel with (among others) Sinema, Salazar and Brian Kemp and even criticized Pelosi for not reaching across the aisle at all as speaker.
No one here has really given a reason why they don’t like her other than the fact that she is a politician trying to be a politician.
