We’ve certainly got an active day here at FDL. Dave Dayen and Teddy Partridge will be covering the Perry v. Schwarzenegger trial starting today in San Francisco at 11:30 ET/8:30 PT, in the fine tradition that landed FDL on the front page of the New York Times for our Libby liveblog.  We have a dedicated page for all trial-related posts, documents, transcripts, live blog and other archives, and will be posting trial videos here as soon as the court puts them up.

Marcy Wheeler is reporting from the North American International Auto Show today, and will be bringing you the latest about the car company you own, General Motors. She’ll be heading to San Francisco tomorrow to cover the trial too.

Later today we’ll also be bringing you the battle of the health care wonks, a video debate between 538′s Nate Silver and our own Jon Walker. They have been engaging in a spirited debate on health care reform in print for several months now, so Dave Dayen decided he would play Don King and get them together. It will begin at at 4pm ET/1pm PT. We are urging Dave to keep the hair.

We’ll also continue our coverage of the story Marcy broke on Thursday, on the failure of MIT economist Jonathan Gruber to disclose that he was being paid by the Department of Health and Human Services for his work justifying the excise tax in the health care bill. It resulted in the New York Times printing a correction over the weekend, saying “Professor Gruber signed a contract that obligated him to tell editors of such a relationship. Had editors been aware of Professor Gruber’s government ties, the Op-Ed page would have insisted on disclosure or not published his article.”

In addition, we’ve got the health care War Room going, and we’ll be directing readers to take action to stop the mandate.  So please join us for what is sure to be a spirited day.
