(CNN) – Do not expect national Republicans to rally around Christine O'Donnell and infuse much needed campaign cash into her campaign for Delaware's open Senate seat. The Tea Party favorite upset establishment backed Rep. Mike Castle Tuesday evening, and GOP officials are concerned that O'Donnell has no chance of winning the seat – once held by Vice President Biden for 26 years – in November.
"Until she demonstrates some viability in the polls we are not going to have any money for her," a top Republican official told CNN. "It is now incumbent on Sarah Palin, Jim DeMint and the Tea Party Express to help support her. They got her here. Now make it happen."
