Contrary to the other Jewish parties, the Bund advocated an electoral cooperation with other Socialists, and not just between either Jewish parties or with other minority parties (in the electoral alliance "
Bloc of National Minorities"). Thence,
Agudat Israel,
Folkspartei and the various Zionist parties were represented in the
Sejm, but the Bund never was. According to Bernard Johnpoll, this was mostly because its potential partner, the
Polish Socialist Party (PPS), was reluctant to appear as a pro-Jewish party. The party obtained 81,884 votes (0.9%) at the
1922 Sejm election, approximately 100,000 (0.7%) in the
1928 Sejm election and 66,699 at the largely rigged
1930 Sejm election. In the autumn of 1933, the party issued a call to the Polish public to boycott goods from
Germany, in protest of the
Hitler regime. In December 1938 and January 1939, at the last Polish municipal elections before the start of the
Second World War, the Bund received the largest segment of the Jewish vote. In 89 towns, one-third elected Bund majorities. In
Warsaw, the Bund won 61.7% of the votes cast for Jewish parties, taking 17 of the 20 municipal council seats won by Jewish parties. In
Łódź, the Bund won 57.4% (11 of 17 seats won by Jewish parties). For the first time, the Bund and the PPS had agreed to call their electors to vote for each other where only one of them presented a list. This however did not go so far as common electoral lists. This alliance made it possible for a Left electoral victory in most great cities: Warsaw, Łódź,
Lwów,
Piotrkow,
Kraków,
Białystok,
Grodno,
Wilno. After its municipal electoral successes in December 1938 and January 1939, the Bund hoped for a breakthrough at the parliamentary elections due in September 1939, but these were de facto cancelled by the
German-Soviet invasion. ==Organization==
