It doesn’t even have to be about politics - this can be lifestyle, philosophy, or movie critique. Maybe a different celebrity for each different thing you’re particularly opinionated on.
I’m fond of Anthony Bourdain’s views on cooking, for instance, and on how to learn cookery. But he’s a bit of a rascal when it comes to how he treats others.
I like C.S Lewis’s views on life, faith, and epistemology.
As for politicians, well, I doubt any politician alive today accurately shares my views. But i could composite from a few; for instance i found it sensible that Jeremy corbyn (UK ex-leader of Labour) wanted to nationalise many things asap no matter the shock to the economy - buying them back presumably becomes harder the more time that passes.
Public I don’t know. Ron Swanson is a fictional character that sometimes feels like he could be a caricature of me.
Ron Swanson is the greatest libertarian thinker ever… so staunch to his ideals, and, since he is not a fascist, he’s open to other people’s political ideas and we see him change his stances on things. I didn’t like parks and rec that much but i loved him.
