I can't say why
@Kathryn doesn't care for her, but I can say why I don't. My liking her or not, IMO, has nothing to do with her qualifications, however. I don't care for Hillary, nor Pelosi, but I think they were fabulous at their jobs, and I'm grateful for their service!
It's that perfect and constant grin. It feels fake. It looks "pageantity," sorority, Ivy League privileged. Something about Hillary and Pelosi runs the same, without the grin.
Let's face it, "presentation" matters more in this era for women as we're just beginning to level off in the equality plane. Three in the political eye that present as very relatable, IMO, are Amy Klobachar, Elaine Luria, and Stacey Abrams. Keep an eye out for them.
