The campaign started after the election was officially announced for 14 November. The pandemic remained a large issue, especially with the rise of the
Delta variant in the country. The anti-corruption parties (
ITN,
DB, and
IBG-NI) were all looking to hold their ground, while the established parties (
GERB,
DPS, and
BSP) wanted to capitalise on public frustrations with the inability to form a government. The elections were widely hoped to bring an end to the political stalemate that had lasted since the
April 2021 elections, after which no government could be formed. This time, there was more pressure on the anti-establishment parties to start negotiating a coalition government after the elections. After the president announced the new caretaker cabinet, the economy and finance ministers who were replaced in the reshuffle,
Kiril Petkov and
Assen Vassilev, announced that they would compete in the November election as part of a new coalition named
We Continue the Change, with the aim of becoming a new anti-corruption force that could form an effective government. The global energy crisis was a large issue in the campaign, with
natural gas prices soaring to record highs. Campaigning parties offered varying solutions to address this, with some supporting more reliance on Russia for energy, while others proposed
domestic nuclear power in the longer term. The campaign was also influenced by the high levels of
inflation in the country, which hit record levels at 4.8% in September, causing public dissatisfaction. Another important issue was
COVID-19 vaccinations. Due to a low vaccine take-up and high rises in the number of cases, the caretaker government implemented a "green pass", also known as the
vaccine passport. The green pass required citizens to provide proof of their vaccination status in several locations such as hospitals, schools and restaurants. The measure was met with widespread protests. On 6 October, the instructions of the Minister of Health and the Chief State Health Inspector for voting were approved, and did not differ from those for the elections on 11 July. Deputy Chairman of the Central Election Commission, Rositsa Mateva, said "there is no requirement for a green certificate for voting in the parliamentary and presidential elections on 14 November." Bulgaria's Central Election Commission accepted the registration of 23 candidates for the presidential elections, announced after the deadline for applications on 12 October. This was the largest number of candidates in a presidential election in Bulgaria since the country began direct democratic elections for its head of state; previously, the highest number was 21, which occurred in 1992 and 2016. The
Organization for Security and Co-operation in Europe (OSCE) announced in a statement that it would send an observation team to the general elections, following an invitation from the authorities of Bulgaria. It noted that the
Office for Democratic Institutions and Human Rights (ODIHR) had previously observed 12 elections in the country, most recently the 11 July 2021 early parliamentary elections. ==Opinion polls==
