I found this answer on a political board….
Either:
– go to a fundraising event held by that party. There will be a basket by the door where people put checks. Instead of a check, put $199 in cash. If they have a guest book, don’t sign it.
or
– mail an envelope with $199 in cash to the party office, with no return address. Put opaque paper around the cash, so it isn’t visible thru the envelope, lest it get stolen in the mail.
or
– walk into the party headquarters, say I want to donate to the party, and hand them $199 in cash. Then walk out. They will ask for your name, address, etc. so they can send you a Thank-you note. Just say that’s not necessary, and decline to give them that info. They will still be polite (& grateful), since you did just donate to them.
P.S. This really isn’t necessary.
I help maintain the database for a political party. We have specific flags on it for ‘Do Not Phone’, ‘Do Not Mail’, and ‘Do Not Email’. And we do mark those flags when requested, and definately pay attention to them when sending stuff. (I just marked a couple dozen as Do-Not-Email this afternoon, based on peoples’ requests.) We pay attention because we don’t want to upset our supporters, obviously. But also, just like you dislike getting unwanted stuff from us, we dislike wasting our money sending it to you if you’re not going to respond.
So you really don’t have to go to this extent to donate ‘anonymously’; just give a donation and clearly state that you want to be kept off their phone call / letter / email lists. They should pay attention to that.
And it always takes less energy for you to hang up the phone or throw away the letter than it took them to make the phone call or mail you the letter.
