IIRC the Kennedy election events were very similar in tone (rock starish). More swooning girls then. Media was slow but there was less of it, so speeches were broadcast and people listened to them. Rhetoric was more formal and poetic then, but less reality based perhaps.
Then, as now, there was a renewed hope for dramatic change for the better, an end to the war maybe, a generational shift to the younger, more progressive culture. The euphoria in these hopeful elections arises from the unexpected possibility that we (well, many of we) just might find ourselves in a world that better reflects our own values and priorities.
Both then and now opportunities opened up for women and minorities to move closer to parity with WASP (white anglo-saxon protestant) men and to have a chance to have our issues raised. Again, after years of corporate greed and government spying, the people today have more common ground than they did in the Kennedy era though, whether they realize it or not. Interesting times.
