NDP Leader Jagmeet Singh was ecstatic as he did a media round last weekend, and deservedly so. He was announcing his latest deal with Trudeau鈥檚 Liberals, one that would bring in the first prescription drug coverage with a federal imprimatur.

Singh used a technique similar to the one he鈥檇 employed when bringing in the first phase of a federal dental care program: obtain something clear and tangible that people can understand. The complicated next steps could come later.

Singh didn鈥檛 get the credit he deserved for prodding the Liberals into respecting their deal that began with a national dental plan for kids. He wasn鈥檛 taking any chances of that happening again, even at the risk of overselling what had been achieved.

This was smart politics and smart policy. Let the technocrats work out the fine print. The top line is: here鈥檚 some good news. If you have diabetes, your medication will be covered from now on. Full stop.

Younger Canadians were also being told that contraceptives would be covered under the Canada Health Act. A more modest yet worthwhile attention to another demographic.

I know that the diabetes drug announcement is really welcome relief for hundreds of thousands of Canadians. It鈥檚 one that hits home personally for me. My dad suffered from diabetes in his later years. He lost both legs. The cost of his medication was exorbitant and because he was self-employed, he didn鈥檛 have private insurance. He and my mom were in a real financial bind.

Canadians often look south of the border and feel understandably satisfied that we鈥檙e not stuck with the type of Medicare patchwork, from province to province, that Americans are saddled with from state to state. But our prescription drug coverage, pharmacare, is as disparate as their Medicare. It makes no sense that life-saving medication is only covered when you鈥檙e hospitalized.

New Democratic Party Leader Jagmeet Singh

Singh and Trudeau have managed to offer up a first example of what could become a crucial new national program. Yes, of course, there鈥檚 political self-interest involved, but that doesn鈥檛 distract from the good that could come of it.

There are massive hurdles to overcome. Without seeing a word of the plan, Alberta premier predictably announced that she鈥檒l 鈥渙pt out.鈥 Quebec will likely do the same but smart negotiating could easily provide the help Canadians in every province need.

This is, after all, provincial jurisdiction. But Trudeau has pulled it off before.

When Trudeau stole another page from the NDP program, on low cost daycare, I couldn鈥檛 have been happier for Canadian women. Yes, I鈥檇 run on that as a key platform issue in the 2015 general election and Trudeau鈥檚 Liberals had dissed it. That said, imitation is the highest form of flattery and Trudeau has become very flattering indeed, towards NDP policy.

Trudeau took a very pragmatic approach that either compensated provinces for existing childcare plans or provided a massive financial incentive to sign up those that had little or none. There have been a few bumps, but overall, it鈥檚 worked.

Trudeau, of course, wasn鈥檛 obliged to follow through on this undertaking in his 鈥渟upply and confidence鈥 agreement with the NDP. He could鈥檝e said no to the pharmacare portion and there were voices of experience telling him to do just that.

Trudeau's 'gamble'

Senior Liberals I鈥檝e spoken to felt Trudeau had a golden opportunity to walk away and show spending restraint. There was no real threat that the next budget wouldn鈥檛 pass, the Bloc had more than enough votes and they鈥檙e in no hurry for an election.

But that would have created a serious perception problem for Trudeau, governing at the beck and call of separatists. Trudeau, by nature, will also avoid leaving others the power to decide. If there鈥檚 going to be an earlier election, it鈥檒l be at a time of his choosing.

In the end, Trudeau played to type, spending more, buying time (with taxpayers鈥 money) and flipping the bird to Poilievre鈥檚 Conservatives.

Trudeau seems to be making a gamble similar to the one that Stephen Harper made when facing him in 2015. Harper鈥檚 campaign bet heavily that if they give Canadians enough time to see how inexperienced and unprepared Trudeau was, there鈥檚 no way they鈥檇 vote for him.

Canadian Prime Minister Justin Trudeau

Harper called the election early and had the longest campaign in Canadian history. Trudeau did well in the debates and ran a good campaign, using that extra time to his own advantage. Harper lost his bet and Trudeau won the election.

The same sense of 鈥測ou must be joking鈥 seems to permeate the Trudeau Liberals right now. They鈥檙e in denial. Poilievre is leagues ahead of them in every single poll but they鈥檝e convinced themselves that it鈥檚 not really happening.

This is similar to Liberal behaviour when Harper came along. 鈥淗e鈥檚 got a hidden agenda鈥 was a rallying cry that was supposed to scare the pants off Canadians. Harper was elected three times.

Poilievre's 'Achilles' heel'

Despite his polls, there is in fact a real danger for Poilievre that his reflex to go low and attack personally will start to wear thin. The history of personal attacks in Canadian politics is not very favourable for those doing the attacking.

Poilievre often manages to score short term political points, but at what cost, longer term? (And, yes, with this newest deal, there will now be a longer term.)

Conservative Leader Pierre Poilievre

When Trudeau announced online harm legislation, Poilievre was amusing if not statesmanlike. He decided to assail Trudeau for his black face frasques, saying that someone who鈥檚 worn racist costumes isn鈥檛 in a position to lecture anyone. He also fired off that for Trudeau, hate speech is 鈥渟peech he hates.鈥

A great line but largely off point. Again, hundreds of thousands of Canadian parents are profoundly concerned with the horrific torrent that hits their kids鈥 social media feeds. Trudeau was talking to all of them. Polièvre was only talking to his base.

Trudeau hit the nail right on the head when he simply rolled his eyes and said that Poilievre was opposing something he hadn鈥檛 yet read. Touché.

When Harper was prime minister, his attorney general, Peter MacKay, acted swiftly to bring in tough legislation against unwanted sharing of intimate photos. It was in reaction to a deeply troubling case of an adolescent who鈥檇 taken her own life. That was leadership.

Poilievre鈥檚 lack of that type of moral certainty seems to be an Achilles' heel. Everything is an excuse for even more smart aleck one liners. He鈥檚 not steering by any guiding star. He鈥檚 done an incredible job of eviscerating his adversaries (and the press) but he wants to be prime minister, not a pundit. His behaviour is beginning to expose an inability to deal with serious issues seriously.

Poilievre recently forced his caucus to vote against a free trade deal with Ukraine. That war-torn nation had worked hard to get the pact with Canada and wanted it badly. Poilievre made an implausible link between that trade agreement and the carbon tax he so hates here at home. His MPs were compelled to reject it, even though that made no moral or economic sense.

The 1.5 million Canadians of Ukrainian descent are unlikely to just forgive and forget. Politics is all about adding. Poilievre seems to think his high polling numbers make him invulnerable and he can throw away votes without consequence.

It鈥檚 going to be interesting to watch Poilievre鈥檚 manoeuvring in reaction to the announcement about diabetes drug coverage. Politics is indeed all about adding. Singh and Trudeau have just added a whole bunch of Canadians who are thrilled to get that relief.

Will Poilievre show a modicum of nuance, or will he just do like usual and exclaim how awful it all is? Canadians will be watching and will now have more time to pay careful attention.
