Let’s start discussing the democratic campaign, since there’s more to talk about. To put in perspective the amount of statistics used in Hillary Clinton’s campaign, it is only necessary to mention that a former Obama staffer declared that he had never seen a campaign that’s more driven by analytics than this one . The democrats use statistical analyses to decide things such as voter contact, where the organizers spend their time, which voters to call, which to reach by social media and which to knock on their doors .
Hillary Clinton has a full-time internal department of analytics . She hires about 60 analysts, all under the guidance of Elan Kriegel, a statistician who runs the campaign’s statistical efforts. He is one of the top campaign advisers and one of the highest-paid ones as well. Kriegel is responsible for many of the top campaign decisions: he and his team were responsible for deciding where and when to place each of the 60 million dollars that Clinton invested on T.V. ads during the primaries. To allocate the resources, the analytics team devised a model that optimized the “cost per flippable delegate,” an interesting KPI that ensured that Clinton always had an edge on the race against Bernie Sanders. All this has been possible in part due to Clinton’s access to a huge Democratic National Committee dataset of voters  . This database has been gathered since the 2008 election, with information about which magazines voters subscribe to, whether they like to vote early, how likely they are to open certain emails, among others, precious information that Kriegel and his associates have surely been using to push their candidate.
Now it is time to discuss the other side of the coin. The analytical efforts of Trump's campaign have been as unstable as his candidate. As early as May, Trump declared to the Associated Press that data was “overrated” and that he intended to win the campaign solely based on the strength of his personality . However, since his poll numbers started to crumble this summer and due to the insistence of his closest advisors, Trump decided to make a final push on analytics .
Trump hasn’t been as open as his rival about his campaign’s data operations, but financial reports show the campaign paid, this July and August, a good amount to Cambridge Analytica for a dataset of voter information paired with consumer data . He has also requested the Republican National Committee database, a 100 million dollar effort the party started four years ago. But even with these massive sets of information at his disposal, the campaign has only had a mere 4 months to put it into use, as Trump did not invest a penny in analytics during the primaries. As such, their digital data-driven operation has made some hilarious hiccups. Some notorious Democratic donors reported to have received invitations to donate to Trump’s campaign . Even Vicente Fox, a former Mexican ex- president, who is not allowed to contribute to American politicians as he is not a U.S. citizen, tweeted earlier in the year that he had received Trump fundraising emails .
This difference between the two campaigns may prove to be crucial for the November 8th outcome. But don’t take my word on it, listen to Zac Moffatt, Mitt Romney’s digital director during his 2012 campaign, a republican who already expressed his worries about the gap they have with the Democratic analytics operation . A few months ago, Moffatt feared that whoever emerged as the GOP nominee would be perilously handicapped when it came to data analytics just as Romney had been compared to President Barack Obama who, like Clinton, had honed an analytics operation more than a year in advance, even taking all their analytical operations to the mid-term elections in 2014 .
This year's election will certainly be pivotal for the use of intensive statistics-based political operations. The many statisticians working on this campaign will surely develop a whole new set of tools that will redefine election cycles for years to come. Sadly, with all the remarkable differences between Clinton’s and Trump’s campaign strategies, consultants and the media will have so many theories to explain the election that the value of the most important data-driven operation ever seen in politics may be overlooked, once again.
