Chalk this up to one more reason (among many) as to why you guys need to get rid of this guy for once and for all.
I want you to compare the two links below. Most states use through their Secretary of State offices an online software system called "Voter View," through which voters are able to check the status of their ballots.
The first link shows you what the landing page looks like where I live in Arizona: https://voter.azsos.gov/VoterView/Home.do
Now look at the same software's landing page for Kansas: https://myvoteinfo.voteks.org/VoterView/Home.do
Compare the two and you will see that what is supposed to be in that big open space at the bottom of the Kansas page are links to "Provisional Ballot" and "Early Ballot" where people can check the status of either type of their own ballots. This means Kobach has intentionally disengaged this part of the software on you guys. The Rethuglican Secretary of State here in Arizona is also despicable, but thank goodness she's not so far gone yet as to do that!
So, where does that leave you? There is one other possibility to check your ballot and that is your specific County Recorder. Check online for your County Recorder's Office (sometimes called the County Elections Department) and see if they offer any kind of ballot checking. Many do this completely separate from the Secretary of State's Office. If none is immediately visible, call the county office (number found right there online) and ask how you can assure your ballot has been accepted.
I hope this helps and I am pulling for you guys in Kansas. GOTV!
