The Constitution's Impeachment Clause applies to all "civil officers of the United States" - not to mention the president, vice president and federal judges. It is not clear who, precisely, is among those considered "civil officers," but the group certainly includes a president's cabinet and sub-cabinet, as well as the senior department officials and the White House staff (those who are issued commissions by the president and serve the President and Vice President).

Lowering the aim of an impeachment effort to focus on those who have aided and abetted, or directly engaged in, the commission of high crimes and misdemeanors, would have all the positives, and none of the negatives, of going after Bush and Cheney. It would not be an effort to overturn the 2004 election, but rather to rid the government of those who have participated, along with Bush and Cheney, in abuses and misuses of power; indeed, many among them have actually encouraged Bush and Cheney to undertake the offensive activities.
Many of these men (and a few women) are young enough that it is very likely that they will return to other posts in future Republican Administrations, and based on their experience in the Bush/Cheney Administration, they can be expected to make the offensive conduct of this presidency the baseline for the next president they serve. Impeachment, however, would prevent that from happening.
It will be recalled that Article I, Section 3 of the Constitution states: "Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States." (Emphasis added.) After any civil officer has been impeached, under the rules of the Senate, it requires only a simple majority vote to add the disqualification from holding future office.
