Most people probably won't encounter this, but it's worth considering as we think about the long-range future of vote-by-mail, which is probably growing, and of the U.S. Post Service, which has been slowly spiraling downward.
The Klamath Falls News & Herald reports about the community at rural Crescent Lake (in far northwest Klamath County, about 70 miles southeast of Eugene), which has lost its post office and the zip code that goes with it, replacing it with another that has resulted in confusion. Getting mail there has become something of a problem.
When time came to vote in the primary election, there were issues getting them because the elections office was set up to use the Crescent Lake address and zip. The ballots were expedited, finally. But when time came to mail them back, the voters had to drive 35 miles to get them sent off.
Given the trend lines of mail voting and postal cuts, this is the sort of glitch that probably needs to be dealt with sooner rather than later.
