Actually, when you think about it like a Googler, you don't even need to lose 1/365th of your revenue. You only need to hit districts where those representatives are voting for SOPA. You can also hit people once, then resume normal business. Maybe do it for an hour or two at a time. You can feather out the carpet bombs.
[Edit] I meant targeting the reps that are voting for SOPA, not against it.
