I don't think Condi is a viable candidate because she has never held an elected office.
Give her 4 years as governor somewhere in the south and she will blow the competition out of the water.
Not being from TX, Hutchison has the image of a wishy washy person who stands for nothing but going along with other people's agendas. She does not project being a "leader".
Historically, governors, not senators, have been the best candidates. What GOP governor is going to emerge with a reputation, a following, an issue, an agenda? with something that will attract supporters and media?
