Hmmm...
Quick pick of random names off the closing list (that I did) showed none with confirmed gifts to Obama, though there were a few gifts to low level democrats.
I don't have time right now, but I'd like to know if a random sampling of those not being closed shows an inordinate proportion of those who gave to Obama being left open. (It's very likely that few of the car dealers gave to Obama, thus if a random choice of those to be closed were made, it would show few gifts to Obama.) I'd need to see an analysis of both lists to make a judgement.
