When Sarah Palin was announced as John McCain's running mate, President Bush said that she "had the executive appearance and that's what it takes to be a capable person...in the executive branch." But like Bush's own vice president, it's not clear that Palin would consider herself to be part of the executive branch.
The Hill reports that it inquired with both Joseph Biden and Sarah Palin about whether they would consider themselves to be part of the executive branch in the next administration. The Hill's Kevin Bogardus reports, "Sen. Biden (Del.) believes the office he is seeking is solely in the executive branch, according to his staff. But aides to Alaska Gov. Palin did not answer the question."
