Also, you don't HAVE to pick more than one.

In my experience that’s where people can get confused. We switched to ranked choice voting in university student government elections and that idea was not well-explained for the first election. We eventually got the hang of it though.

Still a bit surprised that it’s the Democrats objecting to this one. It might be a function of them having a near stranglehold on local DC government, and not necessarily indicative of how they’d react in more competitive states.
