Ukraine's TV president on verge of turning fiction into reality

• Poroshenko's unpopularity is tied to his failure to tackle corruption. The president has suggested the inexperienced Zelensky would be a dream come true for Vladimir Putin.
• What to watch: Zelensky is slated to debate Poroshenko on Friday in front of a crowd of up to 60,000 at Ukraine's national stadium.

Claire Kaiser, an expert on Eastern Europe at McLarty Associates, says that if Zelensky wins, he'll have to build a strong national security team and send an early signal he has a handle on foreign policy.

• "Anyone running the show in Ukraine has the dual challenge of managing the economy and finding some sort of solution to the war in the East," she says.
• Kaiser says Zelensky hasn't sent any signals that he plans to shift Ukraine's orientation away from Europe and the U.S., so while "there will definitely be a getting to know you phase," U.S. policy toward Ukraine is unlikely to change significantly.
