[2] The Nonpartisan Bloc for Cooperation with the Government, a coalition of the Sanation faction - won the highest number of seats in the Sejm (125 out of 444) and 48 out of 111 in the Senate–in both cases, short of a majority.

Unlike latter elections during the Sanation era, opposition parties were allowed to campaign with only a few hindrances, and gained a significant number of seats.

[3][4] The last three elections held before World War II were all rigged in favour of the Sanation forces (the BBWR in 1930 and 1935, the Camp of National Unity in 1938).

[7] The 1928 vote has been studied in relation to the Zydokomuna narrative which portrays the major ethnic minority blocs of Jews as well as Ukrainians and Belarusians as fifth columns and reservoirs of communist support.

Elements of Poland's pre-1918 political elite had discussed the creation of a federal arrangement with regional autonomy for minorities, but after 1922 these plans were scrapped in favor of a unitary state with "less than adequate protection of cultural and education rights for the countries Germans, Ukrainians, Belarusians and Jews".

Among the Jewish population, support for minority parties fell from 65% in 1922 to 33%, while a plurality of Jews voted for Pilsudski's bloc.

[10] Instead, Jews were the strongest ethnic bastion of support for the Pilsudski government, moreso than both other minorities and the Polish majority, with no significant regional differences in the political behavior.

"[11] An alternative explanation holds instead that Jews turned to Pilsudski as a protector in an increasingly volatile political scene.
