The party registered major gains in the election of November 1919, the first to involve all of Greater Romania. The PȚB was effectively in alliance with the Democratic Nationalist Party (PND), which was based in Romania-proper, with the Romanian National Party (PNR) of Transylvania, and the Democratic Union Party (PDU) of Bukovina. The PND leader, Nicolae Iorga, ran for the Assembly on a PȚB list at Orhei, alongside Vasile Stroescu, who was a doyen of the PNM and the emancipation movement. The PȚB also proposed eligible positions to Ion Nistor of the PDU and Iuliu Maniu of the PNR, but they turned down the offer. Artur Văitoianu, the nominally independent Prime Minister of Romania, approached the PȚB to become their candidate in Ismail County. Although favored by Halippa, this attempt was rejected by Inculeț, and became the first of several incidents separating the two leaders.
