"Corruption? Oh, no, dear, this is just 'advanced politics'."

Election season is coming up in Ponyville. Usually, it's a one-horse race, literally, with Mayor Mare winning the election by a landslide, but this time, some competition has arisen.

Filthy Rich has decided to run for Ponyville mayor, and Mayor Mare is not too happy. "Mayor" is in her name, and she's not gonna let this populist plutocrat take her position away from her.

(You) are her secret weapon. A shadow-y saboteur, and one of her seediest connections. She approaches (you) with a sack of Bits and a proposal: ruin Filthy's chances of winning while avoiding suspicion, and there'll be another sack of Bits waiting for (you).

[There's a whole IDW comic arc where this happens. This isn't that, because I just learned that 3 seconds ago.]
