re: Who has been the worst President in your lifetime.

Obama is the worst by far. No contest. He's not only the worst, but the most over rated.

Good presidents are at least capable bipartisanship and compromise to achieve something above their party and the (perceived) good of the nation at the time.

In 50 years, they'll talk about Obama being the first black president. Unless something changes soon, they will not talk about his leadership or what he's done.
