Does any one have any sources where I could go to find info on presidental influence on American pop culture?

I desperately need to know what impact the presidents that served between 1900 and present day, has had on popuar culture. For example, did JFK really get more youths to vote? What has George W. Bush done that has changed the way we act, the way we think, and the way we spend? What about FDR's Fireside Chats? How did that improve American morale during the depression? I REALLY need this kind of information. Anyone that can provide me with this information or can guide me to web sites/ books that deal with specific presidents' impact on popular culture will have done me a great favor.
