Districts each get a seat. That is the part you are not getting.
They do not in the example. The example only knows a single winner.
thus why you think Blue wins it all
I think that blue wins because the example literally tells us that blue wins.
that is NOT how districting and gerrymandering works in the US
And if the infographic said “Gerrymandering as it specifically works in the US only” then that would be relevant.
But it only explains it a general abstract concept. One that can also occur outside the US. This general concept can also occur without US electoral districts that get some seats. It can occur in any voting situation where the overall population is divided into subgroups.
the graphic is a hypothetical that EXPLAINS the real-life situation
Yes, it explains one specific mechanism. Namely changing district shapes to affect the outcome. And the outcome in the example is one color winning.
I do not care how things are in real life, because my comment has nothing to do with the real life situation, only the one depicted here.
It does, but I’m not sure if the president turning the White House into a Disneyland gift shop is much better than collecting his own merch.
