This would have been Senator Hilary Clinton's nominating convention, if her fervent supporters had had their way. As it was, instead of accepting a nomination, the one-time presidential candidate appeared at the convention in Denver to persuade her supporters to switch their allegiance to Senator Barack Obama.

Her daughter, Chelsea Clinton, gave the introduction.

Sen. Clinton's speech showed no regrets or disappointment.

"I'm a proud supporter of Barack Obama," she said to the thousands of delegates gathered in the arena.

Some of her staunchest supporters couldn't suppress tears, because their candidate wasn't continuing on in her run for the White House.

But Colorado superdelegate, Senator Ken Salazar, says it's time for the party as a whole to rally behind Obama.

"She feels in her heart, Barack should be the next president. She wants to see a change, and so she's going to put herself out between now and November, and she's going to ask her followers to do the same," Salazar said.

One Southern Colorado alternate delegate said the only way for Clinton's supporters to forge a future, is to ally themselves with Obama.

According to Jason Degroot, "These people have been working for policies and beliefs for decades. Barack Obama's the one carrying them forward. John McCain's not carrying them forward."

Pueblo's only delegate, former sheriff Joe Torres, says he doesn't have a problem switching his pledged vote, from Clinton to Obama. "I think it's a real benefit that we can choose someone from our party," Torres says.
