Vitaly Klitschko stands two meters tall and punches so hard they call him "Dr. Ironfist."
Now the World Boxing Council's reigning heavyweight champion is fighting a new battle, Ukraine's parliamentary elections.
On Sunday, Ukrainians vote for an entirely new 450-member parliament. Klitschko has come back from Germany to run for parliament, and to pull this massive nation of 44 million people toward Europe.
