We emailed the White House to ask them how they came up with the list, but haven’t heard back. If they ask us for our tipsters’ names, we will ask the tipsters for permission to hand them over. Unless, of course, they tell us not to, like this guy just did:

FOR YOUR INFORMATION ONLY
So far, I have received two of Axelrod’s emails and am convinced it is because I sent emails to both of my senators protesting the health care bill. Am I now on an enemy’s list and is the government able to take over my computer (as reportedly possible when one goes to cars.gov?)

Please do not share my email address with ANYONE (except maybe Major Garrett if he needs it).

I hope this helps any research you are doing in this regard.

(ha!)
