They are nationalist racists trying to cloak themselves with populist leftist ideas. This is the leader of that party:

Örebro Party leader Markus Allard goes to the election on expulsions. He opens to withdraw citizenship and also expel second generation of immigrants – even if they were born in Sweden.
"I'm prepared to cross corpses," he said.

One suggestion that he has is that citizenship and permanent residence permits can be torn up – with reference to "Sweden is the country of Swedes".

In a section of Yoshi's Podcast, Allard develops his view on expulsions and explains that he prepared to "go over corpses" to bring home unwanted immigrants. The host notes that there will be no beautiful sight when, for example, immigrant mothers who have been on maternity leave for 15 years are to be deported together with their children. "It's not going to be pretty to send these people home," he said. Markus Allard agrees, but says: I think you can handle that optics. Even the children will need to be deported, he explains.

He further explains that many of the problems relate to second-generation immigrants. They are going out too. Even if they were born in Sweden, because they have no natural connection to Sweden. They are not Swedes. They have not become Swedes. It says Sweden in the passport, but they have not been interested in becoming part of Sweden. There's a difference. It's a qualitative difference," Allard said

Remember; the Nazi's did the same thing by strategically calling their party the National Socialist German Workers' Party, despite them not being socialist nor a working class party. This was chosen because Socialism was gaining popularity, and thus the Nazi's thought it would help their chances of getting votes and public support.

Generally, “othering” another group and blaming issues on that group while calling for that group to be expelled from a region seems to be how a lot of that sort of thing gets going. Fascism looks at people and sees some of them as people and the rest of them as not people. It gets worse from there.

"Örebropartiet's obsession is "re-emigration" - i.e., sending all immigrants out of the country - which their leader Markus Allard describes as getting rid of "parasites.""

Örebro politician Markus Allard said in a debate that “we have to send out these fucking parasites”.

Note also discussing immigration is very different from discussing re-emigration. Most clearly defining political ideology for this party seems to be populist national conservative. Such an ideology can easily pivot to Nazi like far-right fascism once there is enough support. It is a much easier route to take than going far right from the start.
