It is a portrait of deep frustration. Jeb Bush’s campaign has 10 paid staff members in Iowa, it has made 70,380 phone calls to state Republicans and it has collected 5,000 email addresses. For all that, it has recruited just four volunteers statewide and has identified only 1,260 supporters.

The metrics were shown to campaign donors in Houston this week and revealed on Thursday as part of a detailed strategy memo obtained by U.S. News & World Report.

Upbeat excerpts from the briefing, which called Senator Marco Rubio of Florida “a G.O.P. Obama” and Mr. Bush’s chief rival, had been previously shared with reporters.

But the full 112-page memo, which has more sensitive information, surfaced the day after Mr. Bush delivered a lackluster debate performance and was upstaged by Mr. Rubio.
