As you said, Hawley (Stanford and Yale alumni), JD Vance (Yale alumni), even Trump (from a wealthy family and Penn alumni) are all political elites but also quite popular with the right-wingers. So it's not really about hating the elite, unless by the elite you means a specific subset of Democrat politicians and activists.

How many people would object to being operated on by a prominent Harvard surgeon because that person is part of the elite? How many would oppose their children attending an Ivy League or a selective and private university on the ground of being an elite institution? Do people hate engineering professors at MIT because they're elite or do they actually respect them because of their expertise?

"oh yeah they're all corrupt"

To be clear, I believe that the Harvard and Yale alumni and the other political elites who planned & supported the many coups of the 20th century, started the Iraq war (Bush admin), bombed Libya (Obama) into poverty, etc. are all corrupt and deserve our contempt. It does not have anything to do with corruption scandals either because it's a structural problem where politicians have to cozy up to the defense and oil industries among others to advance their careers and get paid.
