It seems you believe Trump lied because of some obscure definition of the size of a tax cut which no-one uses (Brainwashed much?). Even if we accept the method of measuring a tax cut as a % of GDP, its still a big one, and you are basically being pedantic. YeS Its BiG But ItS NoT ThE BiGGeSt As He ClaiMS

But in terms of marginal tax rate its a big decrease, especially for businesses, it is in fact the biggest ever, which is what he emphasizes. But you wouldnt know because you just read a quote taken out of context by MSM and then i dont even. You are just brainwashed
