Republican Christine O'Donnell has a question: where in the Constitution does it say separation of Church and State?
And she is genuinely amazed that the issue is addressed in the First Amendment.
The moment was captured during a debate at Widener Law School in Wilmington and quickly spread through the blogosphere.
The Tea Party favorite, who is trying to get elected to Vice President Joe Biden's former Senate seat from Delaware, expressed surprise.
"Where in the Constitution is separation of church and state?" she asks.
The audience responded with laughter.
Her Democratic opponent Chris Coons said Donnell's question about the separation of church and state "reveals her fundamental misunderstanding of what our Constitution is, how it is amended."
