Former US Ambassador and Senator George McGovern (D-SD) gave the Washington Post an op-ed published January 8th that summarized the case for impeaching President George W. Bush and Vice-President Richard Cheney.
Here is a link to what I think is the most compelling case yet written to justify removing Bush and Cheney from office.
The political commentator Jim Hightower posted six days later a related approach on his website, which requires a paid registration.
Here is the key paragraph:
"There should be a barrage of investigative hearings, a proliferation of exposes on war profiteering, a surge of subpoenas, a hailstorm of contempt citations, a thousand specific cuts (none harming the troops) in Bush's war budget, an unleashing of Congress's "inherent contempt" power--in other words, a strategic, unrelenting antiwar offensive using all of the unique powers of the legislative branch to march right in the face of BushCheney executive arrogance, reframe the debate, and rally the people."
The progressive news aggregator, Alternet, posted the entire Hightower essay, here.
Hightower noted that he had worked with Sen. McGovern in 1970 as a volunteer organizing members of Congress, and public opinion, against the Vietnam War.
