Fun fact... If your candidates and their campaign is incompetent, then they will fail to do basic things like file bios and therefore won't have one in the pamphlet.

Happens all the time here in WA state as well.  It's not the state's responsibility to write one or get one from a campaign.  It's the campaign's job to submit one.

Here is the process.  Its just not that hard to follow.
