According to the NZ Herald today:
Mr Boscawen said he strongly believed the leader should also stand in Epsom.Cannabis decriminalisation should be a peripheral issue for ACT. Nevertheless denying a position is untenable. It looks dodgy. It's permissible to state that members of a party are divided and until the actual legislation came up, the way the party will vote is unknown. Or that it would be a conscience vote and MPs would vote accordingly. It shouldn't have created the problem that it did back in 2011.
"I believe we should pick our best and most experienced person as the leader and offer that person to the people of Epsom."
"I believe if split that role we send mixed signals that the person we think is good enough to be the leader, is not good enough to be the Epsom candidate."
The last election showed that there was also a risk of conflict.
"We had Don Brash come out and promote the liberalisation of marijuana and while that may have had the support of five per cent of the population, John Banks knew that was fatal for his campaign and strongly opposed it."
The public then witness a conflict between the leader and the Epsom candidate.
But really. Claiming only 5 percent of the population supports liberalisation? This tells me John Boscawen is also anti. Why not just say so? I think ACT would reap more kudos for admitting they are divided on the issue BUT jointly and strongly committed to individual responsibility, low tax, and small government.
TV3′s Campbell Live Mon, 26 Sep 2011, asked viewers “Should cannabis be decriminalised?” and 72% replied yes by text or email.
A new poll has found that almost two-thirds of New Zealanders are against legalising cannabis....another poll by UMR Research  which asked a different question found last month that only 35 per cent of New Zealanders wanted cannabis to stay illegal, 17 per cent wanted it fully legalised and 46 per cent wanted it "decriminalised".
