"an acute observer of politics and politicians"
"icy knifelike reasoning"
"as sharp and incisive as the stroke of a fang"
"frequent penetrative observations"
"a toxic penetrative spray applied to the surface"
"a cold penetrating wind"
"a penetrating odor"
One cannot escape the penetrating smell of fresh paint.
