To robo-call or not to robo-call, that is the question.
If you ask the typical man-on-the-street he'll likely tell you he hates robo-calls, and will tell you that everybody else hates them, too.
Except…
A lot of people who supposedly hate them respond to them…at least when it comes to political robo-calls asking who they support in a particular campaign.
Indeed, the reason so many campaigns use robo-calls for voter ID work is because they are fast, relatively inexpensive and pretty fairly reliable depending on whether or not the person conducting the robo-calls knows what he's doing.
Not perfect, but perfectly helpful for campaigns on a limited budget.
This is not to say you should do robocalls. And it's not to say you shouldn't. It's to say you need to know the environment that your decision is being made in before making your decision.
