I feel like being asked to guess her party is a "don't judge a book by its cover" trap, lol. Looking very closely at the picture, her jacket looks super on point and not cheap, her hair is amazing (based on my wife who has amazing hair it is the farthest thing from cheap), and her nails look colored, with a little moon-shaped uncolored area near the cuticle, aka a Reverse French Manicure. Simple tasteful earrings and one ring that looks like it has a rock on it. I don't think she's in with the current crop of Democratic Socialists.
I'll guess Libertarian or the Green Party. Targeting small businesses with reduced regulation and increased tax benefits is part of the Green's platform.
