FR isn't fundraising at the moment.
Try YET again...
Previously, these add-ons on threads were done during fundraisers.
In the 2nd quarter, it seemed every fundraiser add-on was an anti-Romney statement. That fundraiser seemed to go on forever.
In the 3rd quarter, it seemed there were very few if any attacks on Romney during the fundraiser. That fundraiser went really quickly.
Then, after the fundraising was over, the anti-Romney stuff started appearing, outside of the fundraiser.
This could just be coincidence, or it could be that someone figured out that attacking Romney non-stop wasn’t good for raising money.
