Phone calls advertising for politicians

Speaking of which....I live in Nassau County. Wife just got a robo-call from Ed Mangano (running for county exec) that said, "you haven't voted yet...(we haven't will go later). But how they know and get the call out so fast is frightening.

Though they're saying that you didn't vote yet this is a guess and there is no way they have access to polling data on the day of the election. They might be doing robocalls to people who are less likely to vote over the years or they are just sending out very inaccurate messages. I get calls constantly because I usually vote and enjoyed the old days better when you could screen calls with an answering machine but now they leave messages even if you don't pick up. I used to run phone banks for political groups in the 1980's but calls were much less prevalent and now with computerization I get multiple calls from charities and political groups all day and night long. Well at least after today the political calls will disappear for the next 9 or 10 months.
