Both the BBC and ABC get things wrong. If, on checking, specific information from a usually reliable source is found to be incorrect or unreliable, it can't be somehow made correct or reliable by pointing to the track record of the media outlet. If something is incorrect, it's incorrect. That 70% figure seems way too high, and I'd like to see some polling figures from a reliable source, such as Gallop or Morgan, rather than an unspecified source, which could well be an internet or radio poll. Incidentally, I must congratulate Matilda on her foresight in storing this material for five years, judging by the access date.
