Hillary's "phony speech" was a criticism of Trump's speech (in something of the style of a Trump speech): "Donald Trump's ideas are not just different, they are dangerously incoherent...They're not even really ideas, just a series of bizarre rants, personal feuds and outright lies."
That speech of hers was supposed to be a major foreign policy speech, but — as Hillary-friendly sites have noted — it was short on foreign policy. Here's the NYT:
But although her campaign had described the speech as a major foreign policy address, Mrs. Clinton spent more time ridiculing and dismantling Mr. Trump’s statements than she did elucidating her positions. Here are a few key issues she did not discuss....Ironically, the main argument against Trump has been that he's ridiculing and attacking other people and not providing any policy specifics.
I don't think it works to attack Trump by talking like Trump. For one thing, you're not Trump. How can you suddenly adopt his style? His style emanates from him and is the culmination of a long life of practicing talking like that. Second, if you talk like him, you're a hypocrite if you criticize him for talking like that.
Of course, you can say that other ways to attack him don't work either. That's called checkmate.
AND: Now, a word from Rick Perry: "Donald Trump will peel her skin off in a debate setting...."
