(CNN) - Republican Christine O'Donnell sounded a defiant tone the day after losing her Delaware Senate bid to Democrat Chris Coons, calling her loss a "symptom of Republican cannibalism."
"In other areas, where the establishment Republican didn't win their primary, the local Republican parties united right away. Solidarity goes a long way. Unfortunately, that never happened in Delaware," O'Donnell said during an interview on CNN's American Morning.
O'Donnell has frequently lamented her party's initial reluctance to back her candidacy since she beat longtime Rep. Mike Castle in the Republican primary in September.
"Sen. Cornyn says there was nothing we can do, we didn't have enough money. But if he and Karl Rove had said, look, she is articulate on the issues as many people after watching our debates were able to say…there was verbal support they could have offered as pundits, so to speak, that they chose not to for whatever reason," O'Donnell said.
"I think had Karl Rove immediately come out to support us, had the NRSC even helped us verbally, we could have closed the gap," O'Donnell said.
O'Donnell's primary win shocked her party's establishment, and the Tea Party-backed newcomer initially confronted skepticism from her party's state leadership, as well as many prominent national Republican figures who thought her primary opponent had the best chance of beating a Democrat in the race for Delaware's Senate seat previously held by Vice President Joe Biden.
