Reply #51: OK, so it sounds like they probably did get your info

from this site, then, if your contributions weren't
quite right.

On the anonymity question, I think individual contributions
to parties can be anonymous up to some cutoff point (although
I might be wrong about that, I'm not a lawyer). I'll try to
check it out.

I'm guessing that the cutoff is near $250 as a lump sum,
since I see a lot of my neighbours listed there with $250
contributions ... and I didn't know it. We seem to be
a bit more blue here than I thought :)

Corporate contributions definitely have to be declared,
I think.

If I were you, I'ld definitely see if the PO can help
on the source of the mailing. These are first class jerks.
