The DC establishment seems to "get" that the bushcheney power grab is unprecedented. (e.g., "Power Play" segment in CNN's Broken Gov't series). Impeachment is the remedy. Their fears make no sense, particularly when viewed in the context of history.
We have to keep hammering. Such irrational fear cannot be allowed to stand.

Over the past 200 years, members of the House have proposed articles of impeachment against nine presidents. None of these initiatives reached the ultimate conclusion of a Senate vote convicting the president, and a resulting removal from office. Yet in most instances, the threat of impeachment effectively checked lawbreaking, irresponsible, or incompetent executives. When the Founders devised the impeachment process, they created a deliberately broad standard, which has been accepted through history by successive Congresses and the American people. To prove that an executive official is guilty of “high crimes and misdemeanors,” would-be impeachers make not a classic legal case, but rather a moral, practical—and yes, political—case that a member of the executive branch ought not be allowed to continue behaving badly. As such, when a president or vice president who is threatened with impeachment quits his office, or simply quits abusing it, the process has, for all practical purposes, succeeded.

Of the nine instances when impeachment resolutions were filed against presidents, the opposition party secured the presidency in the next election seven times—most recently when Bush succeeded Clinton. After members of an opposition party pressed for impeachment in Congress, that party has almost always maintained or improved its position in the House at the next general election. After conservative Republicans proposed Truman’s impeachment in the fall of 1952, their party took control of both the House and the presidency. Democrats who moved to impeach Nixon in the summer of 1974 dramatically increased their presence in the House that fall. Even after Republicans bungled their impeachment of Clinton, their party retained control of the House—losing just five seats in the 1998 election that preceded the impeachment vote, and just two in the 2000 election that followed it. And, of course, they also captured the White House.
