Democrat Mary Landrieu is one of the worst Senators in Congress, so many were probably surprised when she took a moralistic tone in going after President Obama in the tax compromise.

Extending the tax cuts for those making more than a million dollars a year is borderline immoral, Landrieu charged. “I’m going to argue forcefully for the nonsensicalness and the almost, you know, moral corruptness of that particular policy,” said Landrieu, walking into a meeting with Vice President Joe Biden and Senate Democrats. “This is beyond politics. This is about justice and doing what’s right.”

Landrieu was fuming about the deal. On her way into the meeting, she slammed the tax-cut extension as a needless giveaway, adding, “That’s all I have to say.” But it wasn’t. She emerged from the meeting a few moments later to continue prosecuting her case to reporters.

“It’s what I’m calling the Obama-McConnell plan. We’re going to borrow $46 billion from the poor, from the middle class, from businesses of all sizes basically to give a tax cut to families in America today, that despite the recession, are making over a million dollars. I mean, this is unprecedented. Unprecedented. I want to repeat that,” she said. Landrieu added, however, that she had yet to make a decision on the final package and was speaking strictly about the extension of tax cuts for the wealthy.

That’s right – she voted for the Bush tax cuts years ago and helped start us on the road to financial ruin, and now she’s citing morality?

Lawrence O’Donnell, however, wasn’t buying her bullshit, so he called her out on it on “The Last Word.”
