Since this thread has come back from the dead, I feel it's worth taking a minute to talk about it.
I don't want -anyone- here to be under any illusion that there's any benefit for our side to be gained by interacting with Brady surveys.
The Brady organization has demonstrated a willingness to outright lie in the past, and I see no reason to believe that has changed.
Those surveys exist for one reason, and one reason only: to demonstrate "popular" support for the Brady position, and they WILL SERVE THAT PURPOSE, no matter what.
If they even bother to actually, you know, process and look at the data, the most reaction you'll get is one of bemusement, "Aw, look at the gun nuts! They stuffed our survey! How predictable", before declaring that data to be invalid and flushing it down the data toilet, leaving only respondents in support of them standing.
