Others below have answered you directly, so I won't bother. I just want to say how puzzling I've always found the question of "leadership ability." Quite frankly, I'm not looking for a leader. I am the leader; that is, I am one of 300 million co-leaders. People who need to be led are evidencing Judge Nap's book.
What I'm looking for is someone who knows the Constitution. The only one in this race who qualifies is Ron Paul. If not him, then I'd prefer a professor of American history or even a constitutional lawyer than any of the other candidates who ran this race. For that matter, a computer that was programmed with the sum total of all knowledge of the Constitution and the history that led to it would be my ultimate presidential candidate.
I don't need leadership from my president. I don't need inspiration from my president. I don't need religious advice from my president. I don't need a "vision for the future" from my president. We the People are supposed to determine the future, not the president. All our "leaders" are supposed to do is handle the day-to-day nuts and bolts and drudgery of governance that keeps the ship afloat; the citizenry can man the wheel just fine, thank you very much.
