"It's a free country and some of the more passionate and less, say, constructive of her supporters are a very, very small minority, might try to do something like that," he said. "No one can be associated with more loyalty and dedication than I towards Sen. Clinton and I will and many of us will be very critical of anybody on the convention floor to do anything that undermines Sen. Obama."
"If that happened, if someone who hogs the microphone or tries to demagogue or tries to be negative, there will no sympathy from Hillary Clinton or loyalists such as myself," Davis said.
However a group of ardent Clinton supporters argued they're not going to stop urging Clinton delegates to try to nominate her at the convention.
"This is a victory but our work is far from done," said Will Bower, co-founder of PUMA, which stands for Party Unity My A**, also affiliated with PUMA Pac, which stands for People United Means Action.
Bower argued a small minority of delegates could switch their vote from Obama to Clinton at the nominating convention -- though that is highly unlikely given there hasn't been any credible push for that from close Clinton allies and there has been no mass exodus of supporters from Obama.
"The last few months Obama has betrayed so many of the core principles that attracted his initial supporters in the first place, whether it's FISA, campaign finance reform, the Iraq War, the town hall debate," Bower said. "All of these things he has thrown under the bus so for us to visualize 4 percent of the delegates changing their minds, we don't think that is unimaginable. And as long as there is a path to victory, we're going to keep fighting for it."
