THE HAGUE, Netherlands (AP) — Socially distanced voters cast their ballots Monday in churches, conference centers and even the national parliament on the first day of a Dutch general election that has been spread over three days to allow people to vote safely during the coronavirus pandemic.

The COVID-19 crisis has been a dominant theme of the campaign, with opposition parties criticizing the government's handling of the health care emergency and candidates explaining how they will rebuild the economy when the virus recedes.

Prime Minister Mark Rutte's popularity soared last year as he guided the country through the pandemic, though it took a hit early this year when the Netherlands became the last European Union country to start its vaccination rollout.

“I think Rutte has done well," said Guido van den Elshout, 72, after voting in the Dutch parliament building in The Hague. "I don't vote for him. He is a good prime minister, but I think he is a bit past his sell-by date.”

Voting Monday started exactly a year after the first Dutch lockdown began and the country is in another tough lockdown amid stubbornly high infection numbers. More than 16,000 people are confirmed to have died of COVID-19 in the Netherlands, with a population of a little over 17 million people.

The conservative People’s Party of Freedom and Democracy, or VVD, led by Rutte, is forecast to win most seats in the 150-seat lower house of Parliament. That would put 54-year-old Rutte first in line to begin talks to form a new governing coalition. If he succeeds, he could become the longest-serving Dutch leader.

The pandemic's ongoing effects were clearly visible in the Dutch capital Amsterdam, where a drive-thru polling station for cars and bicycles opened at a conference center.

Voters could fill out the ballot paper, fold it up and deposit it in ballot boxes without leaving the driver's seat, while cyclists parked their bikes in racks before registering their votes. As an extra hygiene measure, voters could keep or throw away the red pencils that are used to mark ballot papers in the Netherlands.

Voting in Amsterdam, Karin Hoffmeister said she expects a new government “that will handle things differently, be more focused on climate issues.”

The first two days of voting are intended for vulnerable groups to be able to cast their ballot. People aged over 70 also are entitled to vote by mail. Far more polling stations will be open on Wednesday, the official date of the election.

National broadcaster NOS reported that a number of municipalities reported that some postal votes could be invalid because the voters had not followed instructions correctly when mailing their ballot paper.

The broadcaster reported from the small municipality of Bernheze that 1,688 people voted by mail and 143 of the votes could be invalid. Other municipalities reported similar problems, the NOS reported.

The interior ministry said in a statement that it had received reports of “procedural mistakes with postal votes” and has instructed municipalities to save them. It added that it is discussing the issue with the country's electoral council.

A record 37 parties are fielding candidates, from established, mainstream parties, to right-wing populists to a former television presenter leading a party pushing for moves to tackle racial inequality. After votes are counted Wednesday night and into Thursday, the process of forming the next ruling coalition will start.

Christian Democrat leader Wopke Hoekstra said Sunday he favors a repeat of the last four-party coalition, which was led by Rutte’s VVD and also included the centrist D66 party and religious party Christian Union.

Rutte’s government has been in caretaker mode since January, when it resigned over a scandal involving tax officials seeking to root out fraud wrongly targeting families, plunging thousands into debt.

The country’s second largest party is the Party for Freedom, led by anti-immigrant lawmaker Geert Wilders. Polls suggest the party will retain that position, but Wilders is unlikely to be invited to join any coalition because of his outspoken anti-Islam policies.

He has labeled that undemocratic. “We believe from a democratic point of view that the three biggest parties should at least attempt to talk to one another and govern together,” he told NPO Radio 1.

In a televised debate Monday night, Wilders accused Rutte of being weak on immigration.

“A vote for the VVD these days means that even more Dutch people, Mr. Rutte, will feel like a stranger in their own street, a stranger in their own neighborhoods and their own city," he said.

Rutte responded that Wilders fails his own supporters by calling for unrealistic policies to rein in migration.

“You are structurally letting them down because you propose sham solutions," Rutte said.

The polls also forecast that at least two new parties could enter Parliament with a small number of seats — the right-wing populist JA21 and the pro-European party Volt.

Student Mila Kastelein was among those voting for Volt.

For Kastelein, the key issues were “the climate crisis and growing racism but I also think Europe is very important. I'm quite pro-Europe so I voted for Volt,” she said.

Amsterdam Mayor Femke Halsema visited the drive-thru polling station Monday.

"I think is very good because it gives people security. If they are afraid to vote, they can come here and they don’t have to leave their car so they can vote very safely,” she said.
