On CTV this morning, David Frum suggested that she seemed overly coached in her responses.

He said that most media coaches advise their clients that they do not have to answer every question, especially in sensitive areas.

Maybe a better response may have been (IMO):

"Major foreign policy decisions are for the President to make. I leave these type questions for Senator McCain, the Presidential canidate, to address. I am aware that the vice president is required to take on various roles, when asked. I am prepared and am experienced to take on any role, if the need ever arises".

If pressed, she may add:
"Georgia is not a member of NATO. I see a need to speculate on what may or may not happen in the future. If elected, Senator McCain and I will deal with important foreign policy issues as they evolve.

If further pressed:
If elected, suspect we would not solve evolving and important foreign policy decisions through the media. We would do this discussion with partner nations". There is a time to discuss these tpye issues through the media. But, there is a time to keep your cards close to your chest, as not to negatively influence potentally viotile situations. This is one of these issues".
