A bus tour might be a very good idea. At least then she could estimate main street American's opinions and support across the country. Virtually all other forms of information come through media that puts its "partisan propoganda" on the facts.
Talking to the people is a good way main stream Americans can meet Sarah away from the name calling and misinformation of the MSM. They get to meet the person instead of the persona created by the MSM.
Good luck and Best Wishes to Sarah in what ever she decides to do. She will be successful in any position or role becasue she has the values, heart, stamina, and commitment to improving our country.
