Is there any law against submitting a blank ballot? If so you can just write yourself in for every office for which you are eligible, and pick a friend to write in for any others.
If there's a law against a blank ballot AND write-ins are disallowed, you live in a sham democracy where an elite wants to legally compel you to signify your assent to its illegitimate rule, and it is your democratic duty to boycott any such elections in order to highlight their illegitimacy.
