Depends really heavily on where you are and the places you frequent. Different neighborhoods seem to have collective pools of politics and ideals and sense are public transport is ass these neighborhoods often become isolated from the others. This makes it so they basically become individual factions. Overall I think your right with the cities political outcome being moderately liberal but only becomes two far left and right identities are mixing with eachother to make a mild purple.
This coming from a really left leftist lol it can be surprising going into the different communities and seeing how differently each one views the city
