With 29% of voters telling pollsters they haven’t made their minds up for the race slated for March 31, 2019, the field is wide open.

But it’s not too soon to start worrying about the many ways in which the Kremlin may meddle in the election, reads a piece titled "Five Ways the Kremlin Can Meddle in Ukraine’s Big Election" by Mykola Vorobiov, published by the Atlantic Council.

The first way to meddle is easy: support pro-Russian candidates, according to the expert.

Polls show that in spite of Russia’s illegal annexation of Crimea and the ongoing conflict in eastern Ukraine, pro-Russian candidates still enjoy strong approval ratings. Among them are Yuriy Boyko, former vice prime minister and an MP with support at 9.7%, and Vadim Rabinovich, leader of the “For Life” party at 9.5%. Both have over twenty years in politics and their records strongly support the Kremlin.

If Boyko and Rabinovich were to agree on a single candidate in the 2019 presidential election, it would make for a strong ticket, and this potential merger is already drawing worrying parallels to the 2010 election when pro-Russian candidate Viktor Yanukovych returned to power six years after the pro-democratic Orange Revolution and turned Ukraine back toward authoritarianism. The Kremlin will undoubtedly press for the same scenario in 2019 by supporting one of their candidates with large amounts of cash.

There are at least four other ways for Russia to meddle.

First, through its powerful network of opinion makers, journalists, and other experts who work for Russia’s interests in Ukraine, the Kremlin will use its platforms to support a pro-Russian candidate and discredit his or her opponents. Such a message will be spread through various informational platforms and loyal speakers, including those in the West.

Second, the Kremlin may try to destabilize the situation in Ukraine through increased military tensions in Donbas, terrorist attacks, and other violent actions which spread fear, panic, and distrust of the Ukrainian government, including among law enforcement. As a result, many voters may lose their faith in the election process and decide not to vote.

A third possible scenario is through widespread cyberattacks against Ukraine’s governmental institutions, banking system, Ministry of Defense, National Security and Defense Council, and other organizations. In 2017, the computer virus “Petya” hit Ukraine and spread internationally infecting computer systems in the United States. Although these attacks were never formally linked to the Kremlin, they likely came from Russia and can easily be repeated during next year’s election. The presidential administration, to its credit, has started to sound the alarm, and it needs greater support from other governments and the tech community to prepare now.

The hacking of personal emails, as was seen during the 2016 US presidential campaign, is also likely. The country’s electoral system and technologies are vulnerable to outsider penetration, and the Kremlin knows this. It will likely use these weaknesses to hack emails and expose the personal data of key presidential candidates, especially those who seriously threaten the Kremlin.

A fourth possible scenario is the organization of a military coup in Kyiv, which would bring to power far-right and other nationalist organizations including members of volunteer battalions who have military experience in the Donbas.

Another Maidan in Kyiv would likely foment further unrest in the country, and this scenario is music to Moscow’s ears. If a real “Ukrainian junta” came to power in Kyiv, as the outcome of the Euromaidan Revolution was widely portrayed in Russian state media, the Kremlin would use this as a pretext for a “peacekeeping operation” to protect the Russian-speaking population against “Kyiv’s junta.”

A third, violent Maidan would be the most favorable outcome for further Russian military incursion into Ukraine, showing the international community that only Russia can bring order to this “failed state,” while simultaneously keeping Ukraine within the Kremlin’s sphere of influence.
