I will disagree here.
One of the strategies is precisely to get people to understand their elected reps are not representing them, and to vote the bum out.
At some point, it doesn't matter who gets in, if they also get hit with the people emailing them that the only reason they got the vote (and won the election) was because the former representative didn't listen to their constituents. Not because people thought they were better than the other guy, or that people thought they would do a better job.
Remember, once they get into office, they spend an absurd amount of time and capital to stay in office.
Let them know, upfront, that the other guy was voted out - they weren't voted in. Now the focus is on them. Do they want to retain the office next election? or get summarily dismissed, as was their opponent?
