Because as a front-runner, "you are the big target," she said. "I'm still being treated like that — in terms of people coming after me."
Whether Clinton will get to implement any of her ideas as president is far from clear. With Clinton losing 11 contests in a row, there has been a growing number of Democratic voices making her task even harder.
On Thursday, superdelegate Rep. John Lewis, D-Ga., a highly respected civil rights leader and longtime friend of the Clintons, announced he would switch his support to Obama.
"Well, I understand the pressure he's under. It's been very intense. And I respect him," Clinton said. "I consider him a friend. I told him that when I spoke with him."
Does Clinton buy into the idea of Obama as a phenomenon, appealing only to ill-informed voters?
"Well, I wouldn't put it that way," she said. "I think the best description, actually, is in Barack's own book, the last book he wrote, 'Audacity of Hope,' where he said that he's a blank screen. And people of widely differing views project what they want to believe onto him. And then he went on to say, 'I am bound to disappoint some, if not all of them.'"
Does Clinton think that a woman running with Obama's qualifications would have been laughed out of the race at the beginning?
"Well, I know that people have said that. He was in the state Senate, what, three years ago, four years ago? It's hard to know exactly what his positions are because they have changed rather rapidly in that four-year period. But there is something very appealing, and people have a right to vote for whomever they want."
Many thought the race would be decided by Super Tuesday. Now it all comes down to the primaries in Texas and Ohio. Even Bill Clinton has admitted they are must-wins for his wife.
Clinton is optimistic about those next set of contests. "It is not over yet. You know, Tuesday is a really important election. And we're going to see what the voters think."
And the message she says she hears from her friends and supporters is clear: "Don't give up. Don't give up. I'm with you. Stay in this."
