(CBS News) "The Atlantic" Magazine correspondent James Fallows joined "CBS This Morning" on Tuesday to lay out both presidential candidates' weaknesses and strengths heading into Wednesday's first presidential debate.
President Obama is "one of the most accomplished speakers we've heard," Fallows said on "CTM." He added that his time as president has kept him "immersed in every detail of every topic that could possible come up."
As for Romney, Fallows said that he "can be quite effective and disciplined" when he is prepared.
But with strengths come weaknesses, and the president's is that he can come across as being "superciliousness" when he is challenged, adding that the president is "not used to dealing with anyone else as people."
Romney, meanwhile, faces problems "when something comes out of left field," Fallows said.
"Mitt Romney has been debating over the past two years with his opponents. President Obama has been practicing no doubt, but it's harder for a president to do because he's busier and doesn't like being addressed in a challenging way," Fallows said.
Fallows said Romney has one distinct advantage and that is that the challenger "often gets a boost" from just being in the same room as a president.
The art of debating, he said, is "being prepared yet seeming spontaneous and natural of course is the magic."
"When we think back on memorable debate lines, it's never about tax rates," Fallows said after watching more than 30 hours of debates. "It's about the kind of revelations in character and personality and disposition and temperament, and you can see that in how people hold themselves on screen."
