OP, it would be easier to ask the opposite as that list would be shorter. This thread would go on for miles if we tried to list them all. I'll do the ones I can think of off the top of my head.
Lefties of Hollywood:
Damn near every black celebrity. The same is true for most European, Canadian, and Aussie celebrities ( James Corden, Patrick Stewart, Ian McShane , Brian Cox, Hugh Jackman, Michael J. Fox, Ryan Reynolds, Thomas Middleditch, Ellen Paige, Pablo Schreiber, Cate Blanchett, Orlando Bloom, etc.)
Bradley Cooper, Scarlett Johansen , Anne Hathaway, Laura Dern ( Bruce to a lesser extent ), Dick Van Dyke, Cardi B, John Slattery, Eva Longoria ( loves Kamala), Michael Moore, Seth McFarlane, Ashley Judd, The entire main cast of Will and Grace, Nick Offerman, Josh and Seth Myers, Kathy Griffin, Sharon Stone, Katy Perry, Emily and Zoey Deschanel, Jake Gyllenhaal, Nick Zano, Kevin Bacon and his wife Kyra Sedgewick, Harrison Ford, William H. Macy and Felicity Huffman, Alicia Silverstone, Ashton Kutcher , Mandy Moore, J.J. Abrams, Steven Spielberg, Stephen Colbert, Ted Levine (would you fuck me? I'd fuck me) , Connie Britton, Mandy Moore ( big Pete supporter), Scott Eastwood, John Hamm, Elizabeth Banks, Josh Gad, Kristen Bell, Brad Pitt and Angelina, Cher, Lady Gaga, Leonardo DiCaprio , Timothy Omundson, Jamie Lee Curtis, Ryan Murphy and most people who work with him, Jason Ralph ( the vast majority of the Magicians cast too), Most of SNL's current cast and a fuckton of the Alumni.
The one that surprised me was Jason Bateman b/c he's such a douche. Reese Witherspoon finally came out of the closet post-Trump election.
