Yes, and it's good. Nice and intuitive. That's not the hard part.

While I don't have a problem with a "clear selections" button, I hope
that won't be the only way to deselect candidates in a production
system.

A voter will most likely want to "undo" their last selection, without
clearing the others. Consider Cambridge, Massachusetts, with 9 city
council seats and 20 candidates. A voter who accidentally picks the
wrong 10th candidate isn't going to want to hit "clear" and then
re-enter 1-9 all over again. The interface needs good human factors.
And it needs to be similar to the other interfaces. For example, in
a "Vote for 3" race, if I make a mistake on my third selection, I can
clear (deselect) it without affecting the other two selections.
