Blair Lekstrom's resignation Friday capped a lousy week for the Liberals.
Lekstrom gave up his post as energy minister and left the party to sit as an independent because he can't support going ahead with the HST.
He's been wrestling with his obligations, Lekstrom said.
"I believe that my first priority as an elected official is to the people that elect me and then to the political party I represent," he concluded.
And the people were telling, him overwhelmingly and strenuously, that they didn't like the tax or the way the Liberals had introduced it. About 5,000 people have signed the anti-HST petitions in Peace River South; that's more than the 4,805 people who voted for Lekstrom in the last election.
Earlier in the week, Lekstrom had suggested putting the HST on hold for six months or a year to his cabinet colleagues and involving the public in a full discussion of tax options.
But Premier Gordon Campbell nixed the idea. He still maintains the problem is that people don't understand how positive the tax will be. (That seems to make people angrier, since it can be taken as an insult. And it raises the question - if the tax is such a no-brainer, why did the Liberals reject it for years - including through the election campaign?)
Cynics might grumble that Lekstrom left it awfully late. But it remains a principled move, one that will cost him about $50,000 a year.
The biggest impact will be on other Liberal MLAs. They too know their constituents are overwhelmingly opposed to the tax, the secretive introduction, or both.
Lekstrom's example leaves other Liberals to explain why they are willing to ignore the will of the people they represent.
And while one resignation won't shift the premier, two or three might. At the least, they would kick start the race to replace him.
The resignation came in the same week as an Angus Reid Public Opinion poll that should give Liberal MLAs serious concern.
The party's support has dropped to 26 per cent, with the NDP at 46 per cent. That's still above the amazing lows of the former NDP government in its last days, but not a whole lot.
It gets worse for the Liberals. The poll found three-quarters of respondents opposed the HST.
And it found that in Liberal ridings across the province, 45 per cent of those surveyed said they would definitely sign a recall petition against their MLA given a chance; another 17 per cent they would probably sign.
And they might get a chance.
The anti-HST petition looks to be successful. The government would then have several options in responding to it.
But some of the campaigners have said that unless the HST is axed, they will launch recall campaigns in November. Successful campaigns would mean the seats would be declared vacant and byelections held.
It's difficult to stage a successful recall campaign. Proponents would need signatures from 40 per cent of the people eligible to vote in the last election - not just of the number who actually cast ballots.
But there is a lot of anger and a well-organized cadre of volunteers in place.
Liberal MLAs in ridings where the HST opposition is fiercest and margins of victory were small should be looking over their shoulders.
Some will likely be wondering how much they should suffer for decisions they had no real part in making.
It's unlikely the public will be much cheerier in November. Campbell has been dismal in defending the tax and the way it was sprung on British Columbians without analysis or discussion.
And a planned advertising blitz - at taxpayer expense - is likely to make people angrier.
With the legislature shut down, likely until next spring, MLAs are going to be spending a lot of time in their ridings.
They better be able to defend both the tax - and the damaging way their leader has handled it.
Footnote: Lekstrom has acted independently in the past. He voted against the legislation gutting the contracts of public sector unions and opposed the Tsawwassen First Nations treaty. No other obvious potential defectors among the Liberal MLAs come to mind.
