Former Democratic presidential candidate Hillary Rodham Clinton's supporters have not yet decided to stand behind Barack Obama, the presumptive Democratic presidential nominee, according to a new poll released on Tuesday.

The CNN's first general election poll of polls since Clinton quit the race showed that Obama led his Republican rival, John McCain, by 46 percent to 41 percent.

Obama's supporting rate had only one point up from the last poll of polls that were taken before Clinton suspended her campaign, which showed the Illinois Senator leading McCain by 47 percent to 43 percent.

The comparison of the two polls showed "Clinton's decision to suspend her campaign and endorse Obama seems to have produced little or no bouncer for Obama," CNN polling director Keating Holland said.

"Clinton's supporters may need more than one speech to rally behind the party's nominee," he added.

The poll of polls consists of three surveys conducted between June 12 and 16 by separate bodies.
