.....deduction.

The fee for using the taxpayer built rink is $19 on weekend and if under 11 yrs of age $11.  There is a $5 per person fee for watching your child skate.  The site is heavily Trump branded including the Zamboni and maintenance is contracted out.

So the rink cost Trump nothing and in fact realises him a profit and name recognition and was built using a procurement and profit system few taxpayers would condone.  

If this is the system of government you support then Trump is your man, if not, get involved.  No matter what you support, do your own homework diligently.
