Opinion polls gave the PDI-P hope: even with a large proportion of the electorate still undecided, research by two highly regarded pollsters showed that 21 to 24 per cent of voters were committed to voting PDI-P more than a week out from election day.

So there was noticeable disappointment on the faces of PDI-P figures who appeared on television on Wednesday evening to spin the results of the legislative elections held earlier in the day. According to preliminary counts, the PDI-P won around 19 per cent of the national legislative vote — far short of the figure in the high 20s that was its target.

The difference is significant: in Indonesia, political parties can only nominate a presidential candidate if they win 20 per cent of seats in the national parliament, or 25 per cent of the popular vote. If they miss that threshold, they need to form a coalition with other parties in order to get over the line.

The narrative snapped into place on Wednesday night. The Jokowi effect was a flop, some of the governor’s critics gleefully said. One explanation advanced by Jokowi defenders and commentators alike was that former president Megawati’s daughter, Puan Maharani, oversaw a communications strategy from PDI-P head office that botched the opportunity to associate the party’s brand with its most popular figure, Jokowi, by putting herself front and centre in advertising.

The recriminations within PDI-P about how Jokowi’s popularity was or was not exploited, and debates amongst analysts about whether it mattered, will likely drag on for some time now. As Ed Aspinall reminds us, crude national-level results cannot capture the complexity of factors influencing the outcome of legislative elections in Indonesia’s open party list system, where legislative candidates run as individuals as much as representatives of parties, often fighting for votes with their own colleagues.

But the significance of Wednesday’s result for what lies ahead in July’s presidential election should not be overstated.

Make no mistake: Joko Widodo will almost certainly be the next president of Indonesia, notwithstanding PDI-P’s disappointing showing at this election. His closest rival in the presidential race, Prabowo Subianto, is running 30 points behind Jokowi in recent opinion polls. Certainly, the usual caveats about the pitfalls of survey research in Indonesia apply — especially given how much the legislative election results deviated from the surveys. But the truth of the situation is pretty self-evident: Jokowi has a huge lead, and it’s difficult to think of a scenario in which this changes that doesn’t involve a terrible political blunder or scandal, the likes of which have not been seen before in his career.

What the legislative elections indicate, then, is that he will have to govern with a coalition that involves some of the other political parties represented in parliament. On election night, Jokowi again declared his distaste for the horse trading which is part and parcel of how Indonesian coalitions are put together. Nevertheless, with PDI-P potentially falling under that crucial threshold of 20 per cent of parliamentary seats required to nominate a presidential candidate, it will need to offer cabinet seats and perhaps even the vice presidency to politicians from other parties. The expectations of some that a PDI-P landslide would occur, strengthening Jokowi’s hand within that party and giving him a degree of autonomy from the demands of others, have not been met.

This does not halt ‘Jokowimentum’. But after July, when Jokowi will probably be elected president, he will have to deal with the behaviour of political allies-of-convenience. And they may not share his preoccupation with responding to public demands for greater social spending and attacking the corruption built into state budgets. As someone who realises how precious his carefully cultivated reputation for honesty is to his political career — and how fragile it could be — Jokowi must dread the prospect of the corruption scandals that will inevitably hit a cabinet stuffed with party politicians.

Jokowi’s critics within the establishment say that he lacks the experience to be president. What they really mean is: he lacks experience playing politics on our terms. The tension between Joko Widodo’s populist instincts, and the pressures to deal with establishment elites in a system in which patronage politics and deal-making predominate, will be at the heart of his (likely) presidency.
