Now you do.

Over the weekend that’s exactly what Landrieu did. Amid the flurry of late-night amendments before the Senate passed a $3.7 trillion budget which never, ever balances and raises a record amount in taxes (it’s a budget which will never pass in the House but nevertheless will be on the table when the two sides go to conference), Landrieu joined virtually every other Democrat in beating back an amendment authored by Sen. David Vitter which would have created “a deficit-neutral reserve fund to allow for legislation that would require government-issued photo identification to vote in federal elections, as long as costs are fully offset without raising new revenue.”

That was Amendment No. 526, and it was Vote No. 83 on Saturday night. It failed by a 54-44 count basically along party lines.

Joe Manchin (D-WV) was the only Democrat who voted for the amendment. Two Republicans, Susan Collins (R-ME) and Lisa Murkowski (R-AK), voted against it – proving once again how worthless they are.

Tim Kaine (D-VA) and Frank Lautenberg (D-NJ) dodged the vote.

But Mary Landrieu is now on record against requiring an ID to vote in federal elections. Louisiana has a requirement that voters must show an ID in state elections; if an ID isn’t available a voter can bring a copy of a utility or phone bill and sign an affidavit to the effect that you’re actually the person voting that line on the rolls. This vote indicates Mary Landrieu isn’t even on board with what Louisiana does.

Was Vitter’s amendment a trap for Democrats? Of course it was. Just like it’s a trap when Republicans are constantly asked about things like gay marriage or abortion in the case of rape. Democrats aren’t often put on the record about issues like this.

Except this time they were. And Landrieu’s vote says volumes about her commitment – or lack thereof – to the integrity of the voter rolls.

This begs another question – where is Mary Landrieu on Thomas Perez as the Obama administration’s nominee for Labor Secretary? Does she believe Perez’ actions as head of the Justice Department’s Civil Rights Division in suing Louisiana for supposed deficiencies in registering welfare recipients to vote (not to mention shutting down an open-and-shut prosecution of the New Black Panthers for voter intimidation) merit a cabinet appointment?

Landrieu’s answer should be coming fairly soon. Based on her vote Saturday night, which was one of a large number of votes from Saturday night she’s badly out of touch with the majority of Louisianans on, we don’t have great expectations she’ll represent the people of Louisiana well on the Perez issue.
