Newt has a characteristic that would serve him well as president: his broad knowledge of United States history. Presidents need to know what has, and has not, worked in the past.
I don't know if Newt would be a good president, perhaps he would. What I am absolutely sure of is that Newt is the GOP figure whom I would most like to hear as an after-dinner speaker. He comes up with the most interesting ideas of any GOP candidate.
Whether that quality translates into positive presidential performance is a good question. Some of Newt's ideas are real stinkers, such as collaborating with Nancy Pelosi.
