Chancellor Angela Merkel pressed her conservative Christian Democrats (CDU) on Saturday to attract more women to their ranks or else lose their status as one of Germany’s two big popular parties, or ‘Volksparteien’. Speaking on the 70th anniversary of her conservatives’ women’s union, Merkel said the CDU needed to boost the proportion of women in its membership above some 25 percent if it wanted to win more than 40 percent of the vote. “That’s why this is not just a question of women who want to make a career, but it is a survival matter for this Volkspartei,” she said. Both the mainstream political blocs - the CDU and their Bavarian allies, and the left-leaning Social Democrats (SPD) - suffered their worst post-war election results in last September’s national election - 33 and 21 percent respectively. Frustration about the influx of more than a million migrants since 2015 propelled the far-right Alternative for Germany (AfD) into parliament for the first time. Despite a 1996 CDU rule to reserve a third of all party "list" candidacies for women, that quorum was "no longer sufficient for us," Merkel told the Womens Union anniversary gathering at a Frankfurt monastery. CDU men typically won direct, electorate mandates instead of entering parliament via candidacy lists under Germanys proportional system whereby each voter picks a local candidate and exercises a second vote on competing lists of candidates submitted by parties. The Womens Union led by Annette Widmann-Mauz in a resolution Saturday demanded that half of such lists be allocated to women – "placed evenly across the top, the middle and rear of lists." Merkel, 63, is the CDU’s first female leader and the first woman to be German chancellor. Earlier this year, the CDU elected another woman, Annegret Kramp-Karrenbauer, who is sometimes dubbed ‘mini-Merkel’, as party general-secretary, putting her in pole position to succeed Merkel as chancellor. The CDUs Womens Union or Frauen Union, founded on May 1, 1948 in Frankfurt, currently has about 110,000 members.
