" Popular explication of the science of political science, from the early 20th century academic attempts to quantify voter turnout and the efficacy of machine organization to the running arms race between the two major parties to adopt and adapt evolving technologies--direct mail, polling, zip codes, out of state phone banks, data mining, databases and mapping (to the point that ads can be bought on specific bus routes to be seen by a targeted population) and their effect on field work, not to mention the social science research on what makes people vote (the double edge sword of offending them by sending a letter--on plain paper, no shiny--telling them about their neighbors' voting habits with the implied threat that the neighbors know about your attendance at the polls). Unfortunately, this ends just after the 2008 election and thus is not inclusive of the social media blitz employed in the most recent campaigns. "
