Cindy Sheehan Threatens to Run Against Feinstein:

"Cindy Sheehan to Dianne Feinstein: Fillibuster [sic] Alito or I’ll Challenge Your Senate Seat." That's the headline of a press release just issued by Ms. Sheehan. The text begins:

Caracas, Venezuela – Gold star mother Cindy Sheehan has decided to run against California Senator Diane Feinstein if Feinstein does not filibuster the Supreme Court nomination of Judge Samuel Alito. While in Venezuela attending the World Social Forum, Sheehan learned that several Democratic Senators had announced their plans for a filibuster but that Senator Feinstein, who’s up for re-election in November, had stated she would vote against the nomination but not filibuster it. “I’m appalled that Diane Feinstein wouldn’t recognize how dangerous Alito’s nomination is to upholding the values of our constitution and restricting the usurpation of presidential powers, for which I’ve already paid the ultimate price,” Sheehan said.
In a September 11, 2005, essay, Ms. Sheehan said that Senator Feinstein "will also go on our Hall of Shame" because Senator Feinstein has rebuffed three requests by Ms. Sheehan for a personal meeting.

Last fall, Ms. Sheehan dismissed rumors that she might offer herself as a candidate against the re-election bid of Senator Hillary Clinton, whom Sheehan called "a political animal who believes she has to be a war hawk to keep up with the big boys" and "the leader of the pack" of "the pro-war Democrats."

UPDATE: Some commenters were wondering about Ms. Sheehan's reasons for opposing Alito, so here is the rest of the press release:
Sheehan is the grieving military mother whose vigil outside President Bush’s ranch in Crawford last summer focused the nation’s attention on the human cost of the Iraq war. Her son Casey was killed in Iraq in April 2004.

Judge Alito has an extensive paper trail documenting the right-wing political agenda that he has actively advanced, not only as a high-ranking official in the Reagan Administration, but also as a judge. He has publicly supported the "Unitary Executive" theory, a radical notion that the President holds exclusive and inherent authority to execute all federal law. He has supported efforts to curtail privacy rights, including not only privacy from government surveillance and arbitrary arrest, but also other constitutional rights based on privacy, such as reproductive liberty for women. Alito has outspokenly sought to restrict Congress' power, limiting the scope of the Commerce Clause of Article I of the Constitution. In addition, he has consistently applied his discretion as a judge in favor of certain interests and against others. He rarely votes against big business, police or prosecutors.

Sheehan is available for interviews from Venezuela through the contact people listed above. [DK: I have omitted the contact info from this posting.] She returns to the United States on Monday morning and will travel to Washington, DC on Tuesday to participate in an alternative State of the Union event.
