What makes you say that? Hell at 10,000 constituents you borderline don't even need to run ads, just go door to door, personally.

EDIT: Although I suppose the tactic could at that point be turned to buying voters more directly. Spend a ton of money on something that benefits everyone in the district and make it clear that it'll keep coming only if they vote for your candidate, and you might have the same effect.
