From RFE/RL correspondent Christopher Miller in Kyiv:
Volodymyr Zelenskiy, emerging from a black van dressed in a blue suit, white T-shirt, and dark sunglasses, was met by a crowd of journalists as he arrived at the Kyiv Martime Academy to vote on Sunday morning.
Asked by RFE/RL what would be the first issues he would take on if elected president, he answered, "The war and corruption."
As he cast his ballot, Zelenskiy said his wife, who accompanied him to the polling station, had put him in a good mood ahead of time by playing him a song by American rapper Eminem, although he couldn't remember the song. "It went like..." he said, trailing off and bobbing his head.
After being asked who he voted for, Zelenskiy chuckled and dodged the question. "Today will be a victory for Ukrainians, a victory for Ukraine...We have united Ukraine," he said.

Outside the Maritime Academy where Zelenskiy cast his vote, Kateryna Chala, the founder of an IT company who was joined by her three children, told RFE/RL in English that she had voted for Poroshenko.
At the same time, Chala admitted that Poroshenko had made mistakes during his presidency, but ultimately he put Ukraine on a westward path she hopes will eventually lead to membership in the EU and NATO.
"We have a lot of problems...like the high price for gas, [high] prices in our shops...I understand it's not possible to create a miracle and fix everything in just one day," she said, cutting Poroshenko some slack.
"I don't like Mr. Zelenskiy, not only because he doesn't have enough practice in governing, but if you see his comments during the past five years, you understand that he doesn't like Ukraine," Chala said, referring to jokes in the comic's past stand-up shows that poked fun at Ukrainians in a manner that made them seen inferior to Russians and rubbed some here the wrong way.
"His humor isn't positive. He sees Ukrainians as second-level people."
Chala said Zelenskiy seems to live "in his own world" and said she thought he isn't totally independent, adding that his connection to oligarch Ihor Kolomoyskiy, who owns the TV channel on which Zelenskiy's shows are broadcast, disturbed her.
Fearful that things may take a turn for the worse under a Zelenskiy presidency -- including a possible return to full-scale war with Russia-backed separatists in eastern Ukraine and an economic recession -- Chala said, "I even told my children, we need to know English and other languages and to be ready to go our own way.
"Maybe not to go abroad tomorrow, but to be ready to make a new life if we understand that in Ukraine we have bad changes."
