Sure, and if special interest groups didn’t want to be identified as being a donor, they would certainly not come up with a way to hide it, right?
I’m sure they could, but why be that inefficient? There have been over 130k individual donors. I can’t imagine the paperwork required to hide that for Soros @ $150 when he could have just done $2300 and done it with 1/20th the # of donors.
