In Turkey, where President Recep Tayyip Erdoğan’s government has been working to centralize political power, opposition parties have lately had few reasons to be optimistic. This month’s massive rally in Istanbul was a rare exception.

On July 9, after walking for 25 days from the capital, Ankara, Turkey’s main opposition leader, Kemal Kiliçdaroğlu, urged supporters to resist the decline in democratic freedoms. “We will be breaking down the walls of fear,” Kiliçdaroğlu told a crowd of hundreds of thousands. “The last day of our justice march is a new beginning, a new step.” The question now is whether Turkey’s divided political opposition can move beyond rhetoric, and mount a meaningful, unified challenge to Erdoğan’s political hegemony.

The party that Kiliçdaroğlu leads, the Republican People’s Party (CHP), commands a high level of support from Turks frustrated by Erdoğan’s majority rule. But in Turkey’s constrained political environment, and with a popular if polarizing president still at the helm, opposition leaders will face a difficult struggle to maintain the momentum they have established.

When I spoke with Kiliçdaroğlu a few days before his arrival in Istanbul, as he approached the city limits, he sounded as surprised as anyone by the protest’s size, and was keenly aware of the difficulties that loomed. The march was an unplanned reaction to the arrest of Enis Berberoğlu, a former editor-in-chief of the mainstream Hürriyet newspaper, and a CHP member of parliament.

But the march’s more concrete objectives, like its route, became known only after the 450-kilometer (280-mile) protest got underway. By the time Kiliçdaroğlu arrived in Istanbul, marchers were calling for economic equity, educational opportunity, gender equality, and a guarantee of non-discrimination on the basis of ethnicity, religion, or cultural identity. Kiliçdaroğlu, meanwhile, said his goal was the complete remodeling of the Turkish state, with clear limits on executive authority by a re-empowered parliament, an impartial judiciary, and a free media. Forging a coherent political platform from such a diverse array of objectives will test the CHP leadership.

In recent years, spontaneous demonstrations like the one just completed have not delivered the reforms participants have sought. In May 2013, for example, huge crowds gathered to challenge the government’s plans to develop Istanbul’s Gezi Park; the demonstrations ended with no real political impact. A similar outcome is possible this time.

Nonetheless, polling numbers seem to suggest that the public is increasingly behind Kiliçdaroğlu. According to a survey published by Research Istanbul on the day of the rally, support for the march was 43%, which is about 17 percentage points higher than the CHP’s approval ratings. In other words, CHP marchers drew support from outside their base, a sign of Turkey’s deepening disillusionment with the status quo.

Supporters included members of the pro-Kurdish People’s Democratic Party (HDP), 83% of whom approved of the protest. It even resonated with members of Erdoğan’s own Justice and Development Party (AKP); 10% of AKP members surveyed said they supported the march’s objectives.

With his unexpected, unplanned civil disobedience, Kiliçdaroğlu seems to have consolidated his role as the leader of a larger, somewhat fragmented, opposition. In the year since last July’s failed coup, the government’s inevitable but overly heavy-handed response has alienated many Turks. With emergency rule still in effect, a growing segment of the public, it seems, is receptive to the opposition’s calls to strengthen the rule of law.

Erdoğan’s narrow victory in April’s constitutional referendum, which granted the president sweeping new powers to dissolve Parliament, issue decrees, and unilaterally appoint judges, deepened the opposition’s resolve. But it also helped push more Turks into the opposition’s embrace. According to a Research Istanbul survey, among those who voted “no” to the referendum, 85% stood with Kiliçdaroğlu marchers. Tellingly, 7% of those who voted “yes” did as well.

It is too early to speculate whether Kiliçdaroğlu’s march will have a lasting impact on Turkey’s political direction. But, at the very least, it has reframed expectations for the country’s next presidential election, now scheduled for November 2019. But even with the modest gains made earlier this month, Erdoğan remains a formidable opponent, and there is still a long road to walk if Kiliçdaroğlu’s “new beginning” for Turkey is to be realized.
