Bernie Sanders's son falls short in New Hampshire primary
Levi Sanders placed 7th among 11 Democratic candidates in the primary, with only 1.8 percent of the vote after 76 percent of precincts had reported, according to The Associated Press.
Despite his famous father, Sanders struggled to gain traction, facing carpetbagger accusations given he lived outside the district.
He also spent only $12,000, a minuscule sum compared to the money dropped by the election's ultimate winner, The Associated Press reported.
Bernie Sanders did not endorse his son, arguing that he needed to win the race on his own.
Levi Sanders was a strong supporter of "Medicare for All," slamming his opponents frequently for not backing the single-payer health-care system, according to the news agency.
Sanders told AP last week that he was counting on "Medicare for All" to get voters to the polls.
Pappas took home 56 percent of the vote Tuesday night, defeating 10 other Democrats, including Sanders.
While Sanders was widely regarded as the underdog, Pappas was seen as the establishment favorite.
