5. Sen. Amy Klobuchar
Senator Amy Klobuchar is still one of the top contenders in a Biden free race despite her many controversies involving staff. One thing holding Klobuchar back is her previous standing in states like Iowa, where she underperformed significantly. “Her high-water mark in 2020 was 20% in New Hampshire, and she underperformed in Iowa long before Biden really kicked things into gear,” the Post said.
