WASHINGTON (AP) — Americans will elect not only a president on Tuesday, but also his huge team of aides, advisers and bureaucrats who will help the winner run the federal government for the next four years.

Clearly a John McCain presidency would be more conservative than a Barack Obama presidency. Beyond the ideological and partisan divides, however, are differences in style, tone and pedigree that would distinguish one administration from the other.

Obama, if he wins, appears likely to draw several of his top aides, including some Cabinet secretaries, from three key sources: Democratic governors midway through their second and final terms in office; former top appointees of Bill Clinton’s administration; and political pros from Obama’s hometown of Chicago.

McCain, a former Navy officer whose father and grandfather were admirals, is likely to rely more heavily on current and retired military officials. He probably would draw more people from the corporate world, and somewhat fewer people from think tanks and academia, than would Obama, according to people close to the candidates.

Numerous lists of potential appointees are circulating in Washington, Chicago and Arizona. But Democratic and GOP officials warn that both nominees are fully focused on Tuesday’s finish line and probably have made no firm personnel decisions about the administration they hope to run.
