Bob Woodward may be a Bush shill, but his Watergate-era colleague has a different idea.

Carl Bernstein, in Vanity Fair:

Senate Hearings on Bush, Now

orse than Watergate? High crimes and misdemeanors justifying the impeachment of George W. Bush, as increasing numbers of Democrats in Washington hope, and, sotto voce, increasing numbers of Republicans—including some of the president's top lieutenants—now fear? Leaders of both parties are acutely aware of the vehemence of anti-Bush sentiment in the country, expressed especially in the increasing number of Americans—nearing fifty percent in some polls—who say they would favor impeachment if the president were proved to have deliberately lied to justify going to war in Iraq.

John Dean, the Watergate conspirator who ultimately shattered the Watergate conspiracy, rendered his precipitous (or perhaps prescient) impeachment verdict on Bush two years ago in the affirmative, without so much as a question mark in choosing the title of his book Worse than Watergate. On March 31, some three decades after he testified at the seminal hearings of the Senate Watergate Committee, Dean reiterated his dark view of Bush's presidency in a congressional hearing that shed more noise than light, and more partisan rancor than genuine inquiry. The ostensible subject: whether Bush should be censured for unconstitutional conduct in ordering electronic surveillance of Americans without a warrant.

Raising the worse-than-Watergate question and demanding unequivocally that Congress seek to answer it is, in fact, overdue and more than justified by ample evidence stacked up from Baghdad back to New Orleans and, of increasing relevance, inside a special prosecutor's office in downtown Washington.

In terms of imminent, meaningful action by the Congress, however, the question of whether the president should be impeached (or, less severely, censured) remains premature. More important, it is essential that the Senate vote—hopefully before the November elections, and with overwhelming support from both parties—to undertake a full investigation of the conduct of the presidency of George W. Bush, along the lines of the Senate Watergate Committee's investigation during the presidency of Richard M. Nixon.

How much evidence is there to justify such action?

Uh, enough to vividly demonstrate the word "shitload." Go see how Bernstein lays it all out.
