Walker is a good man and has an impressive record as governor. However, no matter how hard I try,I cannot invision him as President. He doesn’t have the world leader presence that commands respect. He comes off as too much of a Mr. Rogers personality.
The prospect of Rand Paul scares the heck out of me from a national security standpoint. His foreign policy is a problem.
Walker would certainly be a vast improvement over what we have now. Hell, Jimmy Carter would be a vast improvement over what we have now, but that is because "what we have now" is setting the bar too damned low.
I think Walker could do a good job. He reminds me somewhat of Harry Truman. Of course, Truman got a lot of instant foreign policy credibility by dropping a couple of nukes and ending WWII.
