CARACAS, Venezuela -- According to a press release issued Friday, Cindy Sheehan has decided to run against California Senator Diane Feinstein if Feinstein does not filibuster the Supreme Court nomination of Judge Samuel Alito.

Sheehan made that announcement from Venezuela where she is attending the World Social Forum.

Sheehan's son Casey died in Iraq in 2004 and she has since become an outspoken protester of the war.

Sheehan is quoted to have said, "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 became well known across the United States when she stood vigil outside President Bush's ranch in Crawford last summer. She demanded to speak with the president about the cost of the war in Iraq.

Sheehan returns to the United States on Monday. She will travel to Washington, DC on Tuesday to participate in an alternative State of the Union event.
