Dan Pfeiffer: “Over the years, third-party candidates have been devastating to Democrats and America. In 2000, George W. Bush wouldn’t have become president without Green Party candidate Ralph Nader siphoning votes from Al Gore. Then in 2016, Jill Stein, also of the Green Party, helped put Trump in office. In Pennsylvania, Michigan, and Wisconsin, the three states that decided the election, Stein’s vote total exceeded Trump’s margin of victory.”“Republicans have tried to re-run this play ever since. In 2020, Republican operatives quietly helped Kanye West get on the ballot (yes, that happened).”“This year, third-party candidates could play a major role in delivering the Senate to Democrats.”
