I do not like robo-calls from political campaigns or any other telemarketers. I know that a call is much less expensive than campaign literature, but a call is an intrusion. And I tend to vote against intruders. And, I’m wise to the trick of push polls. A push poll is where, under the guise of opinion polling, disinformation about a candidate or issue is planted in the minds of those being ‘surveyed’. Push-polls are designed to shape, rather than measure, public opinion.
As for other telemarketers, I have a policy of not doing business with any company that makes cold calls to me. And I always report them to the FTC. (You can file a complaint with the FTC here: http://tinyurl.com/oj25jb )
So politicians, do not call. Send your campaign literature if you must; it makes good compost.
