SCHWERIN, Germany — An anti-immigration party made a strong showing at the expense of Chancellor Angela Merkel's party in her home district Sunday, a repudiation of her open-door policy for migrants.Official results showed the far-right Alternative for Germany (AfD) came in second with 20.8% of the vote, ahead of Merkel's Christian Democrats (CDU) at 19%, the party's worst showing since German reunification a quarter-century ago.
