Three in four Democratic voters support the idea of rivals Barack Obama and Hillary Clinton running as president and vice president in a "dream team ticket" in the November election, a poll showed on Tuesday.
The USA Today/Gallup poll found that 30 per cent of Democrats and Democratic-leaning independents picked as their first choice a ticket headed by Obama while 29 per cent preferred Clinton running for president.
About 45 per cent said that either ticket would be "acceptable."
But 26 per cent found the Clinton-Obama ticket "not acceptable" while 25 per cent did not support the Obama-Clinton team.
The deadlock in the race of the Democratic presidential nomination has fueled speculation that the rivals would team up against the presumptive Republican nominee John McCain in the November 4 election.
The Democratic rivals' next clash is on April 22 in delegate-rich Pennsylvania.
Obama leads Clinton in the delegate count, 1628 to 1497, but neither candidate is likely to capture the 2,025 delegates needed to secure the Democratic nomination at the party's August convention in Denver, Colorado.
