Let's see if this clears up the logjam in future years. This year, there were 17 holdovers and 19 new candidates. Of the 17 holdovers, Morris's time is up and Palmeiro got eliminated. None of them were inducted.
Of the 19 new candidates, 14 were eliminated and three were elected.
That leaves... 17 holdovers for next year. Again. And there will be 27 new candidates.

However, only a handful of those 27 should garner a significant number of votes (Johnson, Pedro, Smoltz, Sheffield,
Carlos Delgado, maybe Nomar).
In 2016, it gets a bit little simpler. Don Mattingly will be off the ballot, and of the new selections, only Ken Griffey and Jim Edmonds will warrant serious consideration. But after that, there will be more tough choices. In 2017, Ivan Rodriguez, Vlad Guerrero, Manny Ramirez and Jorge Posada will join the ballot, with Chipper and Andruw Jones, Jim Thome, Scott Rolen and Bobby Abreu joining in 2018.
So it looks like the 2016 is the voters' best chance to clean up the ballot.
