They don't sway the few undecideds who are still in play in this heated election, and all they do is expend energy "singing to the choir," or falling on deaf ears of the opponents. Indeed, they may alienate the undecideds or at least turn them off marginally from the cause that's being espoused. And since this year, the cause is opposed to an incumbent president, the protests play into his hands.
So--what's a body to do? Walk the streets, register voters, sign up noncommitteds in a silent, compelling way? Okay.
Except that the incumbent has CNN, Fox and all the networks on his side.
So it's Molotov cocktails, right?
