Ms. Clark is not the author of the policy in question but must have known (but did nothing to try to find a longer-term solution before it heated up again) that a dispute would arise with the US regardless of whether the GOP or Democrats won the recent election. 

Her real fault, however, is playing domestic partisan politics with the issue during the current election campaign in ways that (a) set Alberta against BC, (b) interfere with Federal strategy and timing (which has been quite good to date but not showy) concerning both softwood lumber and a wide range of trade disputes with the US, (c) provide cover and motivation for US retaliation (with little prospect of advantage to BC or Canada) targeting the marketing of Canadian wines, cattle, maple syrup, natural gas, beet sugar, grains, etc., etc. to US markets.

We in BC may enjoy her show now but not the longer term effects.
