I'm not sure where you've seen left maximalism in the government so far. You get a choice between right and "let's not disturb the status quo" centrish party. There were barely any strong left-ish opinions for quite a while. That whole idea of a conflict seems really artificial, looking at the news from the outside. Let's hear about the left once someone actually manages to force through things like: more residential buildings overriding nimbys, progressive tax without trivial loopholes, wealth tax, kill gerrymandering, federal level build-out of trainlines, etc.
