Surely the idea is to use the vouchers to fund people who would otherwise not have the resources to run at all - not to give it all to already-established politicians .

I think it's basically a good idea for a democracy - but there should be rules about who can receive the vouchers. As I said... should be newbies only (and not ones who are already rich). I wouldn't make it "financially deprived only" necessarily, I'd allow it for businesspeople and people on otherwise decent incomes, but with a sensible cut-off point for people who could obviously self-fund their campaign.
