A Landrieu campaign aide told BuzzFeed.com that the slavery analogy was based on Cassidy’s appearance in the 2010 film A New America. Cassidy didn’t address slavery, but African-American syndicated columnist Star Parker did. A former single mother who spent years on welfare, Parker appears in the film and attacks the “government poverty plantation.” “With slavery, people generally want out,” she said. “But with welfare, folks are comfortable.”

Tough words, but hardly an endorsement of slavery. Parker is appalled at how Landrieu “dug into the gutter” to try to save her Senate seat. “I did not say slavery was better. I did say that the same political party that enslaved blacks 150 years ago is now full of overseers who ensure that no discussion of freedom from welfare is conducted in African-American communities.”

As for impeachment, another radio ad approved by Landrieu claims that Governor Jindal and Cassidy have “disrespected” President Obama. “If Cassidy wins, they will impeach him.” Neither man has embraced impeachment, but facts are immaterial to Landrieu. Her evidence for Cassidy’s “disrespect” of Obama is that “he refers to him by his last name, constantly.” Instead, he should always refer to him as President Obama.
