So far, nobody has answered my question: How is the energy surrounding Obama any different than that which surrounded Bobby Kennedy 40 years ago?
Also, to address the "all talk" crap...when John Kennedy stood on the capitol steps and promised that America was going to the moon, did he also stand there for the next 2 hours and detail step-by-step instructions on how we would do that? Of course not. He set the goal, and led the country in that direction.
THAT is the type of quality I and many others sense and respond to in Obama. The man is a natural leader, plain and simple. Yes, he has plans behind his words, but anyone with any sense knows that the president can make all the plans he wants, and it won't matter if Congress isn't on board with them. Barack can
lead them towards the goals he wants to accomplish, letting them do their job in working out exactly how to get from point A to point B.
A president doesn't get to legislate (well, no president that actually understands the constitution has, anyway). All he can do is try to set the direction and get people to follow him. Barack's supporters believe he can do that as well as any president since Kennedy.
But I'd still like an answer to my question.

(ETA: I wonder how people in their middle-age viewed that same energy? Certainly gives you something to think about, doesn't it?)
