More voting outside Ukraine:
Also some comments from Poroshenko after voting: "This is an absolutely necessary condition for our moving forward, for the return of Ukraine into the family of European nations and our membership of the European Union and NATO."
Joking around with journalists after casting his ballot, Zelenskyy said he was in an upbeat mood and had "voted for a very worthy guy."
"A new life is beginning, a normal life, a life without corruption, without bribes -- life in a new country, the country of our dreams," Zelenskyy said.

From Chris Miller at Zelenskyy's campaign headquarters:
At Zelenskyy campaign headquarters, the mood is upbeat. Throbbing club music emanates from overhead speakers as campaign advisers mingle with journalists. Table tennis, air hockey, foosball, and PlayStation are on hand for guests, as well as a spread with pizzas, pies, and hors d'oeuvres. There's a full bar for those looking to imbibe. The environment is more party than business or politics.
Sviatoslav Yurash, a 23-year-old Zelenskyy campaign adviser who helps coordinate with civil society, told RFE/RL in an interview inside the campaign headquarters that a first-round Zelenskyy victory is expected. The nonchalance with which advisers carry themselves suggests a high level of confidence.
"We expect to finish first tonight," he said. "But we know Poroshenko will have hidden voters," meaning those who were either undecided coming into today's vote or were too bashful to support their candidate in polling prior to the vote.
Yurash said the campaign is confident that turnout today will be high, which he said should work in Zelenskyy's favor. He said the campaign feels the youth vote will go to its candidate.
The Zelenskyy campaign's pitch to young voters, Yurash said, is basically: "You live in Ukraine…you see our elites have let us down time and time again. We still have the same corruption, the same scandals we’ve seen before."
With Zelenskyy, he added, "now there's a chance for real change" and to elect a leader who is "a magnet for hearts and minds."
The Zelenskyy campaign has spent much of the week leading up to today's vote trying to mobilize young voters. Moreover, great efforts have been made to mobilize Ukrainians living abroad, Yurash said. Particularly, he said, they are looking to win over those who may have moved abroad in search of better economic opportunities but who might return to Ukraine if there is "a change of leadership to get somebody who they will want to come back for."
