Interesting read, especially for those of us who have no idea what technology is available for candidates these days. Clearly every one of us exists in these databases (I assume the GOP has such a thing too) and are connected to other data like what we buy or what we belong to. Seeing this data is shared between candidates I wonder how easy it would be for people to manipulate the data for the benefit of one candidate or another. All it takes is poisoning the entries and you could mislead a candidate&#x27;s plans.
