The 22-year-old said in an interview that his biggest worry was "the collapse of the Euro zone. This would be a catastrophe for everyone. ... Politically I want to push my region, Bavaria, and Germany. Social responsibility and the urge to move things forward - those are my motivations to go into politics," said the engineering student, who is his party's youngest candidate in the upcoming general election.
