American political organisation in 1972

This is fascinating:



I'm pretty sure that with over three decades of rapidly expanding computing power and declining cost the British parties now have a rather more sophisticated operation than the Republicans in 1972. Still, this video clip hints at how grand the organisational effort behind American elections is and I don't think either British party has the broad-based financing that the Republicans were clearly working on even back then.
