Poles Vote in Runoff Presidential Election VOA News 04 July 2010 Boys cast their mother's ballot in a voting station in Mackowa Ruda, northeast Poland, Sunday, July 4, 2010 Photo: AP Boys cast their mother's ballot in a voting station in Mackowa Ruda, northeast Poland, Sunday, July 4, 2010. Poles are choosing their new president in the runoff presidential elections between Parliament Speaker Bronislaw Komorowski and Jaroslaw Kaczynski, twin brother of the late President Lech Kaczynski who was killed in a plane crash. Polls opened in Poland Sunday in a runoff presidential election forced by the death of president Lech Kaczynski. Acting President Bronislaw Komorowski faces a tough challenge from Jaroslaw Kaczynski, the twin brother of the late president Kaczynski, who was killed in an April plane crash in Russia. Mr. Komorowski, a centrist, won 42 percent of the June 20 vote, five percentage points more than his conservative challenger, Mr. Kaczynski. Eight other candidates finished far behind. Mr. Komorowski leads the pro-business Civic Platform Party, which supports the European Union. Mr. Kaczynski has been hostile to the EU and is openly suspicious of Poland's historical enemies, especially Germany and Russia. Exit poll results are expected shortly after polls close, with official results planned for Monday. President Lech Kaczynski, his wife Maria, and 94 others were killed in an April 10 plane crash near Smolensk in western Russia. They were headed to a memorial for 22,000 Polish officers killed by the Soviets in the early days of World War Two. Opinion polls before the crash placed Mr. Komorowski firmly in the lead. But Mr. Kaczynski's support has grown since the accident, which some analysts say has mobilized conservative voters.
