Missouri Attorney General Jay Nixon, who’s running for governor, led a list of unaligned Missouri superdelegates who announced Tuesday night that they’re now with Barack Obama.

Also endorsing Obama: Secretary of State Robin Carnahan and state Democratic Party chairman John Temporiti.

Their support leaves unknown the intentions of two unaligned Missouri superdelegates: party vice chairwoman Yolanda Wheat (wife of the former congressman Alan Wheat) and Missouri NEA official Leila Medley.

Temporiti announced the decisions of  he, Carnahan and Nixon in brief remarks Tuesday night at the Mad Art Gallery in Soulard, where several hundred Obama supporters watched their man — and his remaining Democratic rival, Hillary Clinton — via a giant TV screen.

Also addressing the diverse crowd (young, old, black, white, male, female) was St. Louis city Democratic chairman Brian Wahby.

Here’s the joint statements of Nixon, Carnahan, Temporiti, e-mailed to Political Fix

Attorney General Jay Nixon: “Over the past few months, Sen. Obama and Sen. Clinton have inspired and energized Americans from all walks of life. Across the nation, and here in Missouri, there is a level of excitement and hope that I haven’t seen in many years.

“Sen. Clinton ran a strong campaign and she empowered millions of Americans to reach for their dreams. But after eight years of George W. Bush, Sen. Obama is the right candidate to bring about the change our country so badly needs.

“Missourians are ready for a new direction, both for our state and the nation at large. Families are struggling to make ends meet, and they’re looking for new leaders, with new priorities, to move us forward.  Just like Missourians don’t want four more years of Matt Blunt’s policies at the state level, they don’t want four more years of George W. Bush’s policies at the national level.

“Democrats are already uniting behind Sen. Obama, and over the coming weeks, I expect to see many Independents and Republicans unite behind him as well. I look forward to joining Sen. Obama on the campaign trail this fall as we fight to change the direction Missouri and the nation.”

Secretary of State Robin Carnahan: “As Missouri’s chief elections official, it is my job to ensure that every eligible voter has the chance to have their voice heard at the polls. As of tonight, voters in the final two states have done just that.

“Barack Obama has secured the requisite number of delegates to become the nominee of the Democratic Party.  He has my complete support and will receive my vote at the Convention.

“With the many challenges facing our country – from the high cost of health care and the fragile state of our economy to the war in Iraq and global warming – it is clear that we need a dramatic change in leadership.  Both Senator Clinton and Senator Obama are extraordinary leaders with a passion for change and clarity of purpose that will serve our country well.  It is my hope that in the days ahead both the Senators and their supporters can join together in achieving that common purpose.”

Missouri Democratic Party Chairman John Temporiti: “It now appears that Senator Barack Obama has the delegates necessary to win the Democratic nomination.

“I want to commend both he and Senator Clinton for running an issue based primary that has energized Democrats, Independents and Republicans alike. As Missouri Democratic Party Chairman, I now urge all Americans to unite behind Senator Obama’s campaign and the ideals he has promulgated these past months. Not since John F. Kennedy have I witnessed a candidate that has energized and captivated the American people, especially our young voters, like Barack Obama has.

“The election this November will quite simply come down to whether the American people deserve change or more of the same. It will be a privilege for me to cast a vote at the Democratic National Convention for Barack Obama as our next President of the United States.”

AND, as a bonus, here’s the celebratory comments of U.S. Rep. William Lacy Clay, D-St. Louis, an Obama campaign co-chair :

“This is a historic night for our country and my party.  I am so proud of my friend from Chicago, Barack Obama. 

Sixteen months ago, I came out as one of his earliest supporters. And tonight, as one of his campaign co-chairs, I know that this is a transformational moment, not just for the Democratic Party, but for the future of our nation.

Forty three years ago, when Barack was just three years old, Congress passed the voting rights act. And tonight, the promise of America is being fulfilled.

Barack’s candidacy represents the hope of millions of new voters who believe in, and are exciting about participating in our democracy. 

He also represents the struggle and sacrifice of so many brave people who fought for freedom, equality and full citizenship, and he is the proud son of that legacy.

This election will offer the clearest choice in modern American history. It will be a choice between hope and the politics of fear.

A choice between continuing the failed policies of the last seven years, or changing the direction of this country. A choice between bringing our troops home or continuing a endless, needless war that we should have never fought.

Barack Obama is the positive change that America can believe in. I can’t wait to lead his campaign in Missouri. Barack will win here, and he will help Democrats win up and down the ballot across this country.

Five months from tomorrow, Barack Obama will carry Missouri, and the American people will embrace him as our next President.”
