The supposedly inevitable nomination of Hillary Clinton got more trouble yesterday with a scathing critique and possible challenge from the left.  Former Republican governor and senator from Rhode Island Lincoln Chafee pronounced Hillary disqualified from running and announced he is exploring a run for the nomination himself.  Philip Ricker the of WaPo writes:

In an interview with The Washington Post on Thursday, Chafee did not mince words when he said Clinton's 2002 Senate vote to authorize military action in Iraq should disqualify her from becoming commander in chief.

"I don't think anybody should be president of the United States that made that mistake," Chafee said. "It's a huge mistake and we live with broad, broad ramifications today — of instability not only in the Middle East but far beyond and the loss of American credibility. There were no weapons of mass destruction."

Chafee, who was a Republican at the time, was the only senator from his party to vote against the Iraq war authorization. "I did not make that mistake," he said.

Chafee said that foreign policy — including his indictment against Clinton's hawkish record in the Senate and as secretary of state — would be a centerpiece of his presidential campaign.

I don’t take Chafee seriously as a contender, but he is giving voice and a rallying point to the anti-war crowd, which partially overlaps with the anti-Wall Street crowd attracted to Senator Elizabeth Warren.

A very nice Democrat circular firing squad is forming up.
