My sense is yes.
[S]igns are few that super PACs have had the major impact that both supporters and critics predicted. The flood of spending doesn't appear to have significantly influenced voter opinion in key states in the presidential contest or in top congressional races.This follows the form of the surveys that search for hidden racism by asking you if you think your neighbors might be subject to racism. The theory is that if you think your neighbors might be, well, maybe you are and you're just afraid to admit it. Your answer to the question about your neighbor establishes something about you; it doesn't actually establish anything about your neighbor.
Here, we have a strong sense from the political class that their neighbors are terribly subject to paid propaganda. I think this establishes something about that class -- that they are hungry to buy influence, and fear their opponents outbidding them.
In terms of 'their neighbors,' though, nothing has been established. My sense is that most Americans ignore the stuff as an irritating distraction. We know what we're going to do, and why, and the last person who's going to change my mind is a paid spokesman.
Wisconsin seems to suggest that the vast flood of money and activism moved the needle not at all. I think that's going to prove to be generally true. Your average American has been subject to the manipulations of the most clever geniuses of advertising since he or she was born. They know what they are looking at, and they are hard to move.
