Much of that information is fairly fresh since it will have been produced during redistricting so the parties will know how to get so many Democrats here and there and so many Republicans over yonder.
Telephone number locations are a little more difficult to position, but they can do that too.
The Postal Service is prohibited by law from selling mailing list information, and your ordinary street carrier probably doesn't know enough about you to figure out if you are a Republican or a Democrat anyway.
Think of your plight as just really good dumb luck!
I contacted the Romney campaign in Springfield, offered to do a lit drop in my VERY Hispanic ‘hood. Oh, no, they’ve ID’d “their” voters in my district, I could drop lit there. So an entire area with many new potential voters was overlooked by that campaign. It could be all those voters would have needed was a single visit by a Republican who wanted their vote.
I hope you are right. I think the Democrats aren’t getting the funding they would like to do blanket mailings. That means they have to know who to contact. I know that you worked for the Postal Service. Over the course of years, could a postal employee start keeping track of who receives
continuous literature from the Republicans and other conservative organizations? I’m talking maybe five addresses a day that get sent to the Democrats. Multiply that by months and by thousands of employees. I know that there are laws against that, but our prisons are overcrowded with people who don’t follow the law. It would save the Democrats a lot of time and money. Most postal employees aren’t Republicans.
