John McCain's most urgent problem; his brain
Mr. McCain is working closely with aides like Brett O’Donnell, a former debate consultant for Mr. Bush, to improve his speech and performance. He is working to limit his verbal tangents and nonverbal tics. He is speaking less out of the sides of his mouth, which can produce a wiseguy twang reminiscent of the Penguin from the Batman stories, and he is relying less on his favorite semantic crutch — the phrase “my friends” — which he used repeatedly in his campaign appearances.
So McCain is 'working closely' with George Bush's former speech coach? That explains a lot.
