For UK folks only, on the off chance that anyone reading this is swayable. Do you need any more than my recommendation (which is, FWIW, that AV is marginally better than what we have now, and voting no-I-want-PR is silly)? Then how about JEB? Or the cats-n-dogs version?
And just to pad out the post, a Q-and-A I had with a doubter:

As I read that page, tactical voting is possible in theory (but possibly only under rather implausible conditions: “IRV permits tactical voting if voters have complete and reliable information about the other voters’ full preferences”).
> I have an aversion to hung Parliaments and coalitions.
Ah. I have no such aversion. Indeed, I would marginally prefer it, if that reflected voters wishes. At the moment, no party has a majority of the popular vote, so I would support a coalition, on the grounds that is what people want (well, not what they want, but what their votes lead to).

I think we disagree there, too. Having extremist parties like the BNP crushed by the voting system is (a) unfair and (b) bad, because we rely on that to crush them, rather than actually attacking their arguments and support.

I can go with that.
[Update: well, as you by now know, the result was "no" :-(
* Vote 2011: Greens gain English council seats - Green party leader Caroline Lucas said there is now a sense that the Greens are a real alternative, after gains in the English local elections.
* Vote 2011: UK rejects alternative vote.
* At least Cambridge said Yes.
