Major donors to Mitt Romney’s presidential campaign say that when they call, a response comes quickly. Emails are answered right away. Donors, many of them from the business world, are kept in the loop with weekly conference calls and special access to campaign strategists.

A prime example of the Romney team’s embrace of its biggest donors comes this weekend, when 300 or more of the campaign’s “founding members”—those who have given at least $50,000—gather at a cluster of hotels in Park City, Utah, for two days of meetings with the candidate and his top campaign and policy advisers.
