(CNN) - After 17 months of vigorously promoting her own candidacy, Hillary Clinton made her debut on Thursday as an official backer of Barack Obama.
Clinton appeared before the National Association of Latino Elected and Appointed Officials meeting in Washington and forcefully argued the Illinois senator would be a strong advocate of the Latino community if he is elected president.

Earlier, she told the American Nurses Association that “Anyone who voted for me has little in common with the Republican Party.”
Clinton formally backed her onetime rival nearly three weeks ago, but Thursday's appearances were the first time that the New York senator has advocated for Obama's candidacy publicly in front of voters.
"I know Senator Obama. I have served with him now for nearly four years in the Senate. I campaigned with him for more than 16 months on the campaign trail. I have stood on the stage in 22 debates, but who is counting," Clinton said to laughter.
"Every issue you care about personally, every issue that your constituents care about, every issue that NALEO is fighting for is really at risk," She continued. "We cannot afford four more years of the same. It wont be good for any of us, and therefore we have to be determined to chart a new course, and cannot do that without electing Senator Obama our president."
The NALEO appearance seals Clinton's reentry into the 2008 presidential campaign, 19 days after she called her White House bid quits. It came only hours before Clinton and Obama are set to appear together before powerful Democratic fundraisers that have largely supported Clinton's bid in the Democratic primary. And on Friday, the two senators will head to Unity, New Hampshire, in their first foray on the campaign trail together.
Latino voters overwhelmingly supported Clinton's White House bid throughout the primary season and some Clinton surrogates suggested Obama may have trouble courting the influential voting bloc in the general election.
Specifically, ardent Clinton backer Terry McAuliffe said the New York senator's overwhelming win in Puerto Rico proved Obama had a "problem with the Latino community," and "cannot close in this key core constituency.
But the NALEO audience was all cheers for the Illinois senator Thursday, showing few signs Obama will have difficulty courting the demographic as the general election campaign heats up.
As for Clinton, she told the crowd she "had a lot of fun" campaigning for president, even though there were "some tough times."
"What I remember were all of the faces, all of the people who came out to support me, all of the elected officials who stood by my side, all of the funny things that happened in a campaign that you don't ever predict, but which are memorable," she said.
