Secretary of State Hillary Clinton is squashing rumors of a 2012 presidential run, while trying to raise cash to pay off debt she still has from her 2008 presidential campaign.

In a fundraising letter to 2008 supporters, Clinton asks for $50 in exchange for a commemorative DVD of her "Historic speech at the 2008 Denver Convention" and a special message from the former Democratic Presidential Candidate. $250 or more gets supporters a signed DVD.

Clinton's letter says, "You never gave in. You never gave up. And together, we made history." But now, it may be time for supporters to give up on any future run for office.

While on her trip to central Asia and the Middle East this week, Clinton was asked if she plans to run for President. Her response was pretty clear, "No, I am not."

But, Clinton went even further, suggesting her position as Secretary of State may be her last in public office. "I think I'll serve as Secretary of State as my last public position, and then probably go back to advocacy work, particularly on behalf of women and children, and particularly around the world."

According to the Federal Election Commission, Clinton still owes $479,010. But, she's paid off a significant chunk since where she started in 2008-- $5,943,384.

All the same, die hard Clinton supporters still see hope in some phrases she used this week to deny future plans for public office. They say words like: "I think" and "Probably" could mean there is hope she will step in as Secretary of Defense after Robert Gates retires. Or even more, some supporters still hope Clinton will replace Joe Biden as Vice President on the 2012 Obama ticket.
