you can fool some of the people all of the time

From oral arguments on McCain-Feingold:

Part I
Justice Souter: "So your position is that we ignore context because the voters aren't smart enough to have a context?"(Responding to attorney for the petitioner's argument that polls show most Americans don't know who the vice president is.)

Part II
Kennedy makes a plea for considering context too, but it appears to be chiefly an effort to get the words "biker bar" into the transcript.
