BERLIN — German chancellor Angela Merkel’s conservatives have suffered a historic defeat in a state ballot after almost six decades in power there, partial results showed yesterday, in an election that amounted to a referendum on the party’s stance on nuclear power.
The opposition antinuclear Greens doubled their voter share in Baden-Wuerttemberg and seemed poised to win their first state governorship, according to calculations based on partial results published by public broadcaster ARD.
“We have secured what amounts to an historic electoral victory,’’ Winfried Kretschmann, the Greens’ leader, told party members in Stuttgart.
The Greens secured 24 percent of the vote, with the center-left Social Democrats down 2 percentage points at 23.2 percent, giving them enough to form a coalition government in the state, the results showed.
