undecided

Open and not yet settled or determined.

The question of man's destiny is still undecided.

Uncommitted, not having reached a decision.

The result of the election is in doubt because of a large number of undecided voters.

First, you say, you do And then you don't And then you say, you will And then you won't You're undecided now So what are you gonna do? Now you want to play And then it's no And when you say, you'll stay That's when you go You're undecided now So what are you gonna do?

A voter etc. who has not yet come to a decision.

The real drama came as these two camps fought for undecideds, who literally found themselves in the middle.

[…] but that is a highly flawed procedure if the undecideds differ in major ways from the decideds.
