Your interpretation makes sense if you consider leftist to be a purely relative classification. We don't even need to look outside of the US to understand why that's not a very meaningful way to think about ideology: the Overton window within the Republican party has undergone a substantial shift to the right since the 1970s [1].

Without even loosely-defined characterizations of what a political ideology is and where it falls on our (albeit very imperfect) scale, terms like "leftism" are doomed to a future of being weaponized by their opponents, who themselves shift right and decry moderates as "radicals".

All of that aside, I'd still like to hear your rationalization for her recent appearance as the host of a far-right talk show where she, among other things, referred to the sitting attorney general's investigation of a former President's alleged crimes as one having "all hallmarks of a dictatorship". Is hosting Tucker's program an endorsement of every position he's ever espoused? Surely not. But I'd say it's a level of support akin to giving a speech at a political candidate's rally...
