I'm not assuming Matt Kelty's guilt in bringing this up, but it's something I haven't seen discussed yet. Has anybody considered the possibility of a plea bargain in which Kelty pleads guilty to misdemeanors? That's an idea the candidate might not want to entertain if he's absolutely certain he did nothing wrong. But it would be the least complicated way to ensure the mayoral election still goes on with the two candidates the primary voters preferred.
It is interesting, at least, that the last time special prosecutor Daniel Sigler was involved in campaign finances in Fort Wayne mayoral politics, there was a plea bargain that allowed Mayor Win Moses to continue in that office. Hey, the plea bargain said he had to leave the office. It said nothing about a Democratic caucus voting him right back in.
The prosecution, of course, would also have to want to plea bargain. It's my assumption -- perhaps an Indiana lawyer could speak to the issue -- that there would be less interest in bargaining on the perjury charges than on the campaign-finance violations. Prosecutors tend to take such things very seriously.
