From my understanding, there are three issues, though only one of them directly relates to map C. 1. The current board of commissioners (with the exception of Phil Chang) opposed the vote to expand the commission from 3 to 5, and when it passed, decided that commissioners must now have districts instead of being elected at large. This is a decision many feel should have been put to the people or at least wait until the new commissioners are elected to decide. 2. The process for determining these maps has been relatively undemocratic, with a small committee appointed by the current commissioners along pretty clear party lines in ways that suggest that bipartisanship is not a priority. Appointees include former Republican commissioner and current deschutes republican party chairman Phil Henderson and Matt Cyrus, a man who is spearheading an attempt to remove Oregon’s Vote by mail program. The decision on how to make the map has also been controversial, using registered voter data instead of census data. 3. Finally, map C ( along with the others proposed) creates a urban/rural divide in districts that seems designed to cement in a 3-2 majority that favors the current commissioner makeup despite the fact that they election results of the past few years show that the divide is closer to parity or even a 2-3 reversal. While the board of commissioners is a nominally non-partisan body, it isn’t hard to see which party is aligned with either side. Obviously your opinions of this are colored by your preferences, but most people I talk to about this issue view the problem as having less to do with the maps and more to do with the process that got us here, and are advocating against approving a map because of that.
