Going for Limbaugh

Rahm Emanuel designates Rush Limbaugh as the intellectual force behind the Republicans:

He’s asked for President Obama and called for President Obama to fail. That’s his view. And that’s what he has enunciated. And whenever a Republican criticize him, they have to run back and apologize to him, and say they were misunderstood. He is the voice and the intellectual force and energy behind the Republican Party.

Alinsky's Last Rule:

Pick the target, freeze it, personalize it, polarize it. Don’t try to attack abstract corporations or bureaucracies. Identify a responsible individual. Ignore attempts to shift or spread the blame.

Who is the Democrat's intellectual force?
I designate Alinsky, of course.
