(CNN) - The Delaware Republican party has launched a new robocall the same day voters head to the polls - attacking one of their own.
It features a woman identifying herself as former campaign manager for Republican Senate candidate Christine O'Donnell's and saying, "O'Donnell is no conservative" rather she "just wanted to make a buck."
In the call, a woman introduces herself as Kristin Murray, saying she managed O'Donnell's 2008 Senate bid and alleges: "I found out she was living on campaign donations – using them for rent and personal expenses, while leaving her workers unpaid and piling up thousands in debt. She wasn't concerned about conservative causes. O'Donnell just wanted to make a buck."
Murray is backing O'Donnell's opponent, nine-term Rep. Mike Castle.
She goes on to say, "That's why I left, and why I won't trust O'Donnell with my hard-earned tax dollars."
The state GOP says the call began this morning and went out to likely Republican primary voters.
Christine O'Donnell and the state GOP have been at odds. She alleges state and national Republicans are trying to undermine her candidacy because she wants to shake up the status quo. She complained to CNN about "Republican cannabalism" and her most prominent supporter former Alaska Governor Sarah Palin have called the attacks on her signs of "desperation".
