"Obviously I'm thrilled and honored to have Senator Clinton's support but more than that I honor her today for the valiant and historic campaign she has run. She shattered barriers on my on behalf, of my daughters and women everywhere who now know that there are no limits to their dreams. And she inspired millions with her strength her courage and unyielding a commitment to the cause of working Americans".

A CNN poll released Friday shows that the party is divided after a primary season that stretched over nearly 18 months and 57 contests.

Sixty percent of Clinton supporters said they would vote for Obama, but 17 percent said they would vote for Sen. John McCain, the presumptive Republican nominee and Obama's rival in the general election. Nearly one-quarter, 22 percent, said they would not vote at all if Clinton were not the Democrats' nominee.

The poll's margin of error was plus or minus 7.5 percentage points. The poll was conducted after Obama clinched the Democratic nomination Tuesday.

The Clinton camp made it widely known that she would accept the No. 2 slot if it were offered, but the push was viewed as putting undue pressure on Obama to pick his former rival.

Democratic voters appear to like an Obama-Clinton ticket. A CNN poll released Friday suggested that nearly half of Democrats, 54 percent, would support a joint ticket, but 43 percent would oppose it. The poll's margin of error was plus or minus 4.5 percentage points.
