SZEKESFEHERVAR, Hungary — On thousands of billboards and posters, Viktor Orban’s campaign for a fourth term as Hungary’s leader in elections on Sunday uses a photo showing a long line of migrants hiking through the countryside.

On the image is one simple message, a red sign: “STOP.”

It hardly seems to matter that the migration crisis has largely passed and that there are now more posters in Hungary about the danger of immigrants and refugees than actual refugees and immigrants let into the country this past year.

The poster is in keeping with a campaign that has been rife with dirty tricks, false news stories, vicious personal attacks, conspiracy theories and perceived enemies all around.
