Donald Trump would be making a big mistake if he knocked Hillary? out too early. As things stand, she is essentially a shoe-in for the democratic nomination. The only thing that could change that is if the party infrastructure abandoned her, which they won’t do for the fake Indian, the real socialist, or the irrelevancy from MD. But if Trump started landing knock-out blows on the Hillary? campaign, which he could easily do, he may force the democrat parties’ hand.
He beats Hillary? easily in the general, should it come to that. The left will do everything they can to derail Trump, because, if they do, then Bush wins the nomination and gets destroyed by Hillary!, credibility issues notwithstanding.
I think you are quite right. Hillary is doing just fine destroying herself and needs no help from anyone. Indeed, attacking her too early would be a terrible mistake.
