Member of the Assembly of Vojvodina

Vaš was elected to the Vojvodina Assembly for Zrenjanin's sixth division in the 2000 Vojvodina provincial election, the first to be held following the downfall of Serbian and Yugoslavian leader Slobodan Milošević. The LSV participated in this election as part of the Democratic Opposition of Serbia (DOS), which won a landslide majority victory.^[2]

Vojvodina's electoral system was subsequently reformed, switching from a first past the post model to one in which half the assembly seats were selected by proportional representation and the other half by run-off elections in individual constituencies. Vaš was re-elected in the 2004 provincial election for Zrenjanin's redistricted second division as a candidate of the LSV-led Together for Vojvodina alliance. Following the election, this alliance joined with the Democratic Party and other groups to form a new coalition government, and Vaš again served as a supporter of the provincial ministry. He was vice-chair of the provincial agricultural committee in this period.^[3]

Vaš was defeated in his bid for re-election in Zrenjanin's second constituency seat in the 2008 election. (He was also included in Together for Vojvodina's electoral list in the same election, receiving the nineteenth position.^[4] The alliance won five proportional seats. During this period, mandates were distributed at the discretion of successful parties and coalitions and were often awarded out of numerical order. Vaš could have been selected for a new mandate by virtue of being included on the Together for Vojvodina's proportional list, although in the event he was not.^[5][6])

He received the thirty-eighth position on the LSV's electoral list in the 2016 provincial election. By this time, Serbia's electoral system had been reformed again, such that all seats were determined by proportional representation and mandates on successful lists were awarded in numerical order. The LSV won nine seats, and he was not included in its assembly delegation.^[7]

Municipal government

Vaš has served at different times on Zrenjanin's municipal assembly and municipal council (the latter being the executive branch of the municipal government).^[8][9] He was stripped of his city assembly mandate in December 2012 under very controversial circumstances; this decision was subsequently overturned in court and his mandate returned.^[10][11]

Hungarian National Council

Vaš led his own electoral list for the elections to Serbia's Hungarian National Council in 2014. The list won one seat, and he served on the council for the next four years.^[12] He did not seek re-election in 2018.

Elections for the National Assembly

Vaš has sought election to the National Assembly of Serbia on two occasions. In the 2007 Serbian parliamentary election, he received the forty-fifth position on a coalition list that included the LSV and was led by the Liberal Democratic Party (LDP).^[13] The list won fifteen seats; Vaš was not selected for a mandate.^[14] He later received the 149th position on a coalition list led by the LDP, the LSV, and the Social Democratic Party in the 2016 Serbian parliamentary election.^[15] By this time, mandates were awarded in numerical order; the list won thirteen mandates, and he was not elected.
