Rep. Alan Grayson (D-Fla.) taunted Sarah Palin today as a "wild Alaskan dingbat" who knows nothing about policy.

The comments come in response to Palin's speech at a Republican fundraiser in his home district on Friday.

At the time, Palin had this to say:

"[W]hat can you say about Alan Grayson? Piper is with me tonight, so I won't say anything about Alan Grayson that can't be said around children. But thank you, Florida, for allowing candidates in a contested primary to duke it out over ideas and principles and values, all with the same goal, and that is unseating those who have such a disconnect from the people of America. That's what the goal is here in this race against Alan Grayson. Please fight hard, and do this for the rest of the country. Fight hard, and send a conservative to Washington, DC."

Grayson responded with a snarky email to supporters.

"I look forward to an honest debate with Governor Palin on the issues, in the unlikely event that she ever learns anything about them," he said.

The email continues: "Scientists are studying Sarah Palin's travel between Alaska and Florida carefully. They hope to learn more about the flight patterns of that elusive migratory species, the wild Alaskan dingbat.
