RFK was against the vax and the Kennedy family has disavowed many of his positions. Tulsi also not a main line liberal. But these were close.
You may want to refine the language you use in this post. There are virtually no liberals left. The democrat party is run by authoritarian, left wing, Marxists. You will not find any liberals in the bunch. The republican party is run by authoritarian, left wing, pseudo-Marxists. They are 100% in lockstep with each other and the so-called debates they have in Congress are nothing but window dressing. Pelosi and McCarthy will shred each other on the chamber floor then with drink cocktails together and laugh all the way to the bank. Obama runs around shredding the rich, then buys a $12 million beach front home which sits on 30 acres. Then you get dumbasses who actually Obama cares about them.
