Hillary Clinton will deliver a highly anticipated speech Tuesday night."](CNN) - For a moment, the spotlight will be back on Sen. Hillary Clinton as she takes the stage Tuesday for her last solo "hoorah" of the 2008 presidential election.
Even though she's not Tuesday's keynote speaker, all the attention will be on her as she steps into a role that's a far cry from her original convention dreams. "Tuesday night is Hillary night," one Democratic source told CNN.
The next day, the Democratic senator is expected to release all her delegates to Barack Obama, bringing her White House run to an end.
