Today is Super Tuesday and if you live in one of the 14 states voting in a presidential primary (and stste/local races) today, know this: if you have a disability, ANY disability, you are entitled to ask for any accommodation required so that you may cast your ballot. That includes and is not limited to seating at the voting machine, a helper of your choosing to accompany you to the voting machine, and to help you cast your ballot.
Remember, voting is your RIGHT (unless you are a non-citizen or felin), not a privilege afforded a select few.
Your disability, physical, developmental, or mental is not legally allowed to deny you your tight to vote.
If you encounter an issue, contact your county election commission while still at the polling place. Google it.
