She doesn't use that word, but spinelessness is certainly what Ivins describes
"Sen. Clinton is apparently incapable of taking a clear stand on the war in Iraq, and that alone is enough to disqualify her. Her failure to speak out on Terri Schiavo, not to mention that gross pandering on flag-burning, are just contemptible little dodges"
Ivins says the majority of Americans believe the war in Iraq is a mistake and the U.S. should get out, and a majority are also in favor of raising the minimum wage, repealing President Bush's tax cuts, imposing a windfall profits tax on big oil companies and reducing the deficit not by cutting domestic spending, but by reducing Pentagon spending or raising taxes.
"That is the center, you fools," Ivins tells Hillary and the Democrats. "WHO ARE YOU AFRAID OF?"
The Wikipedia entry for the Austin-based columnist summarizes her career:
Her articles have appeared in Esquire, The Atlantic Monthly, The Nation, Harper's, The Progressive, The Progressive Populist, and Mother Jones. She has been a commentator for NPR, The NewsHour with Jim Lehrer, and 60 Minutes.
This is not the resumé of one who understands the political center. Ivins is right about HRC's evasiveness, though.
Update: Free Press has Ivins' complete article.
