He is rather difficult to define in this sense. The link between policy and rhetoric is not always straightforward with him and, quite frankly, he talks a lot of nonsensical *******s. Many of his moves are indistinguishable from most Republican Presidents but the way he goes about it is rather different. Or at least the way he describes it is.
His 'unconventional' approach is what people admire. Even if it leads to conventional actions.
