http://www.bloomberg.com/politics/articles/2016-09-08/super-pac-telegraphs-battleground-strategy-to-clinton-campaignIn announcing its plans for an “aggressive $4.2 million persuasion canvass” across three states—Pennsylvania, Nevada and North Carolina—the LCV Victory Fund has taken the unusual step of including in a press release the specific ranges of microtargeting scores that define the voters it will attempt to sway in Clinton’s favor and against Trump. It amounts to a direct and precise signal to Clinton’s campaign, state parties and other super-PACs not to bother duplicating those efforts, or perhaps to layer on specific digital or direct-mail communication targeting those individual voters.
