Former Connecticut senator and vice-presidential candidate Joe Lieberman has died at the age of 82. Lieberman was a leading backer of the 2003 invasion of Iraq. He also helped kill the public option in the Affordable Care Act and fought efforts to expand Medicare eligibility. In 2000, he became the first Jewish vice-presidential nominee on a major party ticket when he ran as Al Gore’s running mate. In 2008, he endorsed Republican Senator John McCain for president over Barack Obama. In his memoir, McCain said he was sorry he didn’t choose Lieberman as his vice-presidential running mate over Sarah Palin.
