Another major figure of the Iraq War, former U.S. Central Command chief John Abizaid, has also found a home at Hoover. Past Hoover fellows, including notably Secretary of State Condoleezza Rice, who were tagged to serve in the Bush administration, include Stephen Krasner at the State Department and John B. Taylor at the Treasury Department. The think tank's ties with the Reagan administration were similarly strong. Reagan advisers associated with Hoover included Secretary of State George Shultz, Attorney General Edwin Meese, and National Security Adviser Richard Allen. Margaret Thatcher and Newt Gingrich have also been Hoover fellows.
Hoover became an ideas factory for George W. Bush before he was elected president. In the summer of 1999, Bush, then the governor of Texas and in the early stages of his presidential campaign, paid his first visit to California as a candidate. At the time, Bush's campaign was at pains to portray him as a moderate, "compassionate" conservative who would soften the hard edges of Republican economic and social policy. But a few analysts looked beyond the rhetoric to take a closer look at the advisers who provided the intellectual foundation of his campaign, and in the process saw signs that Bush was not the post-ideological moderate he appeared to be. The Christian Science Monitor noted that one of the biggest tipoffs was Bush's close association with the Hoover Institution, which had already "emerged as the early core of Mr. Bush's brain trust."
