So you can give her the benefit of the doubt and say she meant "a one time savings of $20,000.00 tax dollars".
Now some believe if it wasn't caught - or if it was let's say, Lancaster they would have used it in their campaign literature next time. It would read something like this, "Lancaster Supervisor saved taxpayer $20,000.00 a year in her first term."
Then again others would say - they won't reduce the number of Town owned/tax supported vehicles - so where's the savings. Shell game !
We can't assume Politicians are all alike - now can we ?
