How much is Republican presidential candidate Donald Trump’s golf club in East Fishkill worth? About one-third of what it is assessed, according to papers filed by the business mogul’s Trump National Golf Club, Hudson Valley, in Stormville. Less than a month before Trump announced his bid for president, Trump National Golf Club, Hudson Valley, filed a grievance in May 2015 with the town to reduce the private golf club’s assessed value by 66 percent.
