I'd call soap vegetable (possibly veg/animal) but that's me. Still worth asking.

Darren] Thanks - well spotted.

[Darren] No.
[Darren] Still No.
[Raak] No.
[Kim] No.
[Irouléguy] YES it is indeed dental floss; remember, you don't have to floss all of your teeth, just the ones you want to keep.
I was hoping more of its qualities would come out but it was a race through the bathroom that got it in the end, thanks to CdM's astute observation. hmmm...

Over to Irouléguy

ah, just too slow... I thought of toothpaste first, but realized it suffered from the one-word problem, and so went for my general question instead.

Sorry for the delay, y'all - I'm off work so only switching the computer on intermittently. So, our answer is ABSTRACT. No colour clues, but with a connection to tomorrow's elections.
CdM] Is it a Higgs boson? No
Darren] Is it something you'd want to show your friends? Possibly

Gusset Login] Opinion Poll(s)? No
Darren] Is it a vote? OOH - close *audience breaks into prolonged applause*
all] A broken promise? No
Kim] A political party? No

ImNotJohn] A tactical vote?
flerdle] A protest vote?
Both equally close, but not exactly right

(mind you, i don't expect either of these two to be it, because the terms are probably confined to Aus, because of the preferential voting system; see here and here. Just think of the fun you'd have if you got preferential voting in the UK. woot.)

Darren] A wasted vote? Close, but no cigar
CdM] a transferable vote? Almost certainly not
all] postal vote? As close as the other close guesses
flerdle] An informal vote? Possibly
flerdle] A donkey vote? No
So that's what a donkey vote is. I always thought it was the loyal vote for a long-standing member - because healw-healw-healways gets elected sorrysorrysorry
Raak - A spoiled vote? Almost certainly not

[Irouléguy] That deserves a thwap. *thwap*

goodness, how many are there?

flerdle] *thwap* Ouch
flerdle] A casting vote? Almost certainly not.
goodness, how many are there? GOOD question

Tuj] A vote for a specific party? As close as anyone else has got, but no
Raak] A majority? No
Chalky] Does the answer contain the word 'vote'? GOOD question - No
Gusset Login] A proxy vote? Close, but no
Gusset Login] An illegal vote? Almost certainly not
Gusset Login] A Pop Idol vote? Definitely not
One of the guesses above contains the answer
