A question of ethics

When a school board member is running for re-election, is it appropriate (ethical? legal? fair?) to wear a polo shirt denoting a current position on the Richland 2 School Board while campaigning?

Was the shirt paid for with public money and provided by the School Board to the trustee? (Hint - I don't ask a question to which I don't already know the answer.)

Could this shirt be worn within 200 feet of a polling place by a candidate on the ballot?

Could a facemask bearing any campaign message be worn within 200 feet of a polling entrance?

A quick check with the S.C. Department of Revenue State Tax Lien Registry today reveals that Shadd still owes $45,880 in unpaid income taxes on five personal income tax liens dating back to 2014. One lien was filed in 2014, one in 2017, two in 2019, and one in 2020. 

EDITED 10/19/20. I heard that some payment had been made but, according to https://dor.sc.gov/liens today, the total due on five liens is $46,255.85.

According to SC BIZ NEWS, "The Revenue Department said it exhausted efforts to collect the debts before the names were published, sending letters and making personal contact to attempt to get delinquent taxpayers to comply.   https://scbiznews.com/news/government/77984/

Well, that's a joke. If the State DOR cannot collect monies owed to the State, then get out of the way and turn collection efforts over to private enterprise.

Shadd was elected Board Chair on June 30, 2020. Why would the Board have a tax debtor as Trustee, much less the Board Chair?
