Nearly 99% of WA ballots are accepted, what's going on with the 1% that aren't?

When I say the one percent, what do you think of? Is it the ultrawealthy? A phrase coined during the Occupy Movement? Is it the second wateriest form of milk on the market? This story is about a different group of one percenters, it’s primary election season, after all, and we’re talking about voters who have their ballots rejected in Washington. Over the last decade, around 99 percent of cast ballots were accepted.But of those one percent that were disqualified, the Secretary of State's office noticed a trend: certain demographic groups had higher rates of rejections than others.  That’s something the office wanted to know more about, so they teamed up with University of Washington researchers to better understand whose ballots were rejected and why.
