He's is not going to completely stop taxing on gambling winning but from the likes of what someone said about the threshold of amount to be won before tax is applied, he could increase it to a higher amount, it could be above the $5k but to completely eliminate the tax will be impossible and the reason I think so is because there are so many gamblers over there that are gambling for the purpose of making money and not just for fun like most of us here would say gambling is for fun, many people are gambling for the money.
It doesn't matter to the government why we do that, where there is an opportunity for them to tax then they will. If they don't want the tax then they should give tax relief dor medicines not to the gambling rewards or for the movies or whatever things that people do as a part of entertainment not really for their survival.
