Sometimes you hear something on the radio that makes you want to go back to the days before moving pictures, which if you don't own a TV is really easy to do. I heard
Campaign '68 a few days ago on NPR and after at end of the hour felt like I really knew the '68 election and the drama behind it. The show paints a detailed picture of the most pivotal election of a tumultuous decade.
The website has a useful timeline and
extensive collection of links. Great pages dedicated to each candidate including a short biographic video and specific audio clips.
You probably can't, and shouldn't, play the show in it's entirety but the website and radio show are a great resource.
