Mr. Scholz defended his comment as a lighthearted attempt to convince more people to get their inoculation against Covid-19. “If some people don’t want to laugh, but get upset, maybe it has something to do with their ratings in the polls that aren’t very funny,” he said.
Long the traditional rivals of the center-right conservatives, the Social Democrats spent 12 of Ms. Merkel’s nearly 16 years in government as the junior coalition partner in her government, influencing many of the policies passed, like a national minimum wage and billions in Covid relief.
Mr. Scholz, who was initially dismissed as a viable candidate for chancellor, has surprised the conservatives with his strong showing. Headed into the race, the Christian Democrats thought their biggest challenge would be the Green Party and its 40-year-old candidate, Annalena Baerbock, who has campaigned on a promise to usher in an era of change.
Mr. Scholz, 63, has understood that after four terms of prosperity and relative stability under Ms. Merkel, Germans still value a feeling of security. He has focused his campaign on pledging to ensure jobs and working to shore up social stability by fighting child poverty and keeping housing prices in check.
“A new beginning is needed,” Mr. Scholz told Parliament on Tuesday. “I hope, and I am sure, that it will succeed.”
