On Sunday, Greece is preparing for an election to determine the governing party for the next four years. Despite polls indicating that the ruling New Democracy (ND) party is likely to win, the opposition remains optimistic about their chances of victory.

Greece is gearing up for an election on Sunday to determine who will govern the country for the next four years, as the opposition remains optimistic about their chances of victory despite the polls indicating that the ruling New Democracy (ND) party is likely to win.

In recent weeks, surveys have pointed to a rebound in the popularity of the ND, which saw a downward trend in the aftermath of a deadly Feb. 28 train accident that killed at least 57 people near the northern town of Tempi.

The party's leader and the incumbent prime minister asked Greeks to give him a solid mandate to form a single-party government, promising greater prosperity, stability, and safety. He said a new Greece was already rising thanks to his government's policies, which he touts as bold and realistic.

The main opposition SYRIZA, on the other hand, has built its election campaign on two major pillars, pointing to corruption and wiretapping scandals, the latter of which has become known as Greek Watergate, accusing the government of severely damaging the rule of law and democracy under its tenure and vowing to restore democracy and institutional integrity in Greece.

The declining purchasing power of working- and middle-class Greeks was also in the sights of the party, which argues the economic policies of the ND aggravated income inequality.

Criticizing opinion polls that show the ND ahead, SYRIZA has said its support is more significant than surveys indicate.

While it has suggested that all left-wing parties in parliament band together to form a progressive coalition government, vast ideological divides between them mean the likelihood of such an administration is slim.

The social democratic PASOK-KINAL, led by Nikos Androulakis, is forecast to be the third-largest party in the new parliament, distinguishing itself from the ND and SYRIZA with its pro-Western foreign policy and market-oriented economics. As a result, many surveys and media reports indicate that the party may be a kingmaker in forming a coalition government led by either the ND or SYRIZA.

But, some members of its members consider SYRIZA too far-left, while others oppose cooperation with the ND over the surveillance scandal. This can result in PASOK refusing to join either a potential coalition.

The Greek Communist Party (KKE), the oldest political party in the country, has distanced itself from the other parties it accuses of being established. Led by Dimitris Koutsoumpas, It has dismissed the possibility of taking part in any coalition government. Nevertheless, it appears poised to become the fourth-largest party in parliament, owing to its traditional appeal in some prominent trade unions and young people and its loyal voter base.

MeRA25 of former Finance Minister Yanis Varoufakis, known for his anti-establishment solid and Eurosceptic rhetoric, is also likely to pass the electoral threshold of 3% and be present in the new parliament.

But, its particularly harsh stance against neo-liberal economic policies makes it a less-than-ideal coalition partner for SYRIZA, which has already become a party of the center.

Likewise, the Greek Solution, a far-right, populist party led by Kyriakos Velopoulos, is expected to retain its presence in the parliament but is unlikely to play a role in any coalition due to its pro-Russian and extreme nationalistic and religious rhetoric.

Under those conditions, a second election by early June appears a strong possibility.
