If you think about his steadiness under pressure, the excitement that his young family has brought to the White House, and his ability to use language to inspire his countrymen, there is some resemblance to JFK. So, too, the cool demeanor.
That he still seems self-confident and still enjoys the job is reminiscent of FDR. FDR was once asked how he was able to sleep with all the tough decisions he had to make. He answered that so long as he knew he had gathered all the information possible and had considered the question fully, then he put his head on the pillow and went straight to sleep. Obviously, the combination of problems that Obama faced turned out to be far more difficult than he had foreseen. Yet, he has not seemed terribly rattled and has been able to juggle a lot of complex things.
There is one way he reminds me of LBJ and that is in setting large goals. LBJ was once asked, when he was deciding to go for the Civil Rights Act in 1964, why are going to do that? It will split the party. His response: What’s the presidency for if it doesn’t tackle big problems? Obama, too, has set a number of interconnected big goals. When criticized for trying to do too much, his reply was similar to LBJ’s: That’s what I’m here for.
