For 10 years, I've been watching a trend to manipulate elections through premature "call" of the race by a media outlet. See below for predictions on what may follow a media call for either candidate in Massachusetts.
The media "call" can be manipulated because the public doesn't know that projected winners come from a system that is not even a governmental source! In fact, the media "calls" elections based on data from just one media outlet -- usually a quiet little division of the Associated Press that occupies a little corner somewhere and answers very few questions. Volunteers call in result reports to the corporation. The reports are often inaccurate (see below for examples). The names of these volunteers are not part of the public record. We will never get the list of names for those who will call in the 351 numbers which will result in "calling the election" for Tuesday's Massachusetts election.
HOW THE MEDIA "CALL" MAY ULTIMATELY CONTROL POLICY
If the race is "called" for Republican Scott Brown, expect to see a rush from Republican lawyers to claim that Brown has the right to vote immediately, instead of Paul Kirk who is current interim successor to Ted Kennedy. If that fails, look for an attempt to force abstention on the Massachusetts vote while stall tactics play out.
Sixty votes are needed. If Coakley is called and installed, they've got the 60. If Brown is called and stalled, they've got 59. Either way, the media "call" on Massachusetts is going to be under exceptional political pressure.
ISSUING FALSE NUMBERS TO THE MEDIA TO CREATE A FALSE "CALL"
In the recent controversial NY-23 race, volunteers in multiple wards called in zeroes instead of votes for Conservative candidate Doug Hoffman. There WERE votes, but they called in zero and later said oops. This was not a plausible oops, because the zeroes were not called in randomly for various races, nor did the zeroes spread themselves among different candidates. Doug Hoffman had false zeroes reported while votes were called in for the others. Incorrect figures provided to the media resulted in a margin which appeared thousands of votes larger than it actually was, goading Hoffman to concede prematurely.
In the Florida 2000 presidential election, impossible numbers were provided to the media producing exactly the margin needed to "call" the race for George W. Bush. Minus 16,000 votes were reported for Al Gore, and (not knowing the margin was false), Gore conceded privately to Bush and nearly conceded to the nation.
In New York City's 2008 presidential primary, more than 50 wards falsely reported "zero" votes for Obama (but not for Hillary), creating a superficially low result on Election Night.
In Maine's 2009 election, the media reported called-in results for Lewiston and Augusta, two of Maine's largest cities, for seven ballot questions each with two possible choices (7x2=14 results per city), a total of 28 vote results for the two cities. Not a single one of the 28 results was correct, and eight were off by large margins.
The media "call game" is a political game that can be played dirty, and in Massachusetts, the media "call" could ultimately control national healthcare policy.
Usually, these premature calls can be unraveled if they are incorrect because elections aren't certified for several days and winning candidates aren't installed into office for a month or more. But in Massachusetts, because of the special situation with an imminent vote on a controversial bill combined with a temporary senator, the media call can create an undemocratic mess.
