BREAKING: Obama is "Most Liberal" Senator

The National Journal today announced that Barack Obama was the most liberal member of the US Senate in 2007. Hillary Clinton, on the other hands, ranks 16th.

Here's what they said:

Sen. Barack Obama, D-Ill., was the most liberal senator in 2007, according to National Journal's 27th annual vote ratings. The insurgent presidential candidate shifted further to the left last year in the run-up to the primaries, after ranking as the 16th- and 10th-most-liberal during his first two years in the Senate.

Sen. Hillary Rodham Clinton, D-N.Y., the other front-runner in the Democratic presidential race, also shifted to the left last year. She ranked as the 16th-most-liberal senator in the 2007 ratings, a computer-assisted analysis that used 99 key Senate votes, selected by NJ reporters and editors, to place every senator on a liberal-to-conservative scale in each of three issue categories. In 2006, Clinton was the 32nd-most-liberal senator.

In their yearlong race for the Democratic presidential nomination, Obama and Clinton have had strikingly similar voting records. Of the 267 measures on which both senators cast votes in 2007, the two differed on only 10. "The policy differences between Clinton and Obama are so slight they are almost nonexistent to the average voter," said Richard Lau, a Rutgers University political scientist.

While this may be great news to us Democrats, it was not too good news for a Democrat from Massachusetts four years ago:

As the battles for the 2008 Democratic and Republican presidential nominations have raged, the candidates have blasted each other for taking positions that are out of line with party dogma. Obama has repeatedly challenged Clinton's 2002 vote authorizing the Iraq war, labeling her foreign policy "Bush/Cheney-lite"; Clinton has pointed to Obama's "present" votes on the abortion issue in the Illinois Legislature to raise questions about his support for abortion rights. Meanwhile, Republicans have battled over the strength of their conservative credentials on taxes, immigration, and national security.

When the campaign shifts into the general election, however, the two nominees may each seek to cast their opponent as a party extremist. During the 2004 presidential campaign, for instance, Republicans attacked Sen. John Kerry, D-Mass., as an extreme liberal, including by pointing to his ranking as the most liberal senator in NJ's 2003 vote ratings.

Will this label cement his support around those progressives who viewed him as a "conservative Democrat?" Will this help JRE supporters, clearly the most progressive in the party today, come to Obama's side? I hope so.

Update: I will leave interpretation of this to the comments section. However, based on one of the comments concerning how this is "inaccurate" due to the number of missed votes of both candidates, I want to update this ---

Members who missed more than half of the votes in any of the three issue categories did not receive a composite score in NJ's ratings. (This rule was imposed after Kerry was ranked the most liberal senator in our 2003 ratings despite having missed more than half of the votes in two categories.)
