Erick over at RedState has already gone over how nasty these people are, but my primary reaction is slightly different.
What James O’Keefe has demonstrated here is that Battleground Texas isn’t competent enough to make sure that anything told to them stays in confidence. If you are a Texas Democrat and you have ever spoken candidly to a Battleground Texas staffer, let this act as a not-friendly observation: you may have been recorded. You cannot trust any assurances from Battleground Texas that it did not happen in your case. And you had better hope that you didn’t say anything stupid, vile, and/or prosecutable.
Have a nice day!
