The 12 key leadership traits hang on the wall at the Oskin Leadership Institute at Widener University: Know what you stand for. Soar with your strengths. Develop an agile mind-set.

Keep learning and growing. Walk your talk. Know when to follow and serve. Hold others accountable. Create positive energy. Ask great questions. Have the courage to experiment. Inspire a shared vision. Leave a legacy.

With the battle for leader of the free world near its end, how do Donald Trump and Hillary Clinton measure up?

Asked to list the presidential candidates' strongest traits and weakest links, Arthur Schwartz, the institute's founding director, offered his view.

Trump, he said, excels when it comes to inspiring a vision. Ask an undergraduate what Trump stands for, and "build a wall" is a likely response, he said.

"Mr. Trump is maybe not inspiring a shared vision, but he is inspiring a vision," Schwartz said. "If you ask the same question, what does Mrs. Clinton stand for, it's not as clear."

Clinton, he said, gets high marks for legacy. She has made the world a better place for women and children, he said, starting from her earliest work with the Children's Defense Fund.

"Her footprint is clear, compelling," he said. "I couldn't even begin to tell you Trump's legacy."

On the weak side, Clinton hasn't been asking great questions, Schwartz said. Trump has, he said.

Trump's weakness? His failure to create positive energy, Schwartz said.

"I just don't think he knows how to do it," Schwartz said. "I don't think he wants to do it."
