The US media have made an agreement in the last few decades to not broadcast the votes for each state until the polls close for that state in order to not influence voters who have not as yet gone to the polls. But this year State magazine has said to hell with that agreement, they are going to report running totals, because they say that news organizations have a duty to report the news as they get it and not conceal it.
Their Votecastr tracking system takes the vote totals as the precincts report them, and since who voted is not a secret, votes are assigned to each candidate based on historical patterns and micro-targeting data about each voter. They are supplementing this data with poll observers and are doing it for seven states that they think are worth watching closely: Florida, Ohio, Nevada, Iowa, Pennsylvania, New Hampshire, and Wisconsin.
Of course, you should not make too much of the totals because you do not know how many supporters of each candidate will voted later.
Look on it as a way to pass the time and an alternative to listening to the talking heads prattle endlessly. At least this is actual data. Currently, as of 3:00pm ET, Hillary Clinton is leading in all seven states.
