“He tells people to have high hopes & low expectations. Under the folksy Heartland mayor is an ambitious resume-padder. Behind the liberal rhetoric, he stands for the status quo,” Stein tweeted.

“How can he win if Black voters see through the hype?” she asked.

Pete Buttigieg is what neoliberalism looks like. He tells people to have high hopes & low expectations. Under the folksy Heartland mayor is an ambitious resume-padder. Behind the liberal rhetoric, he stands for the status quo. How can he win if Black voters see through the hype? — Dr. Jill Stein (@DrJillStein) February 5, 2020

Stein's comments were made after a majority of the official results from the Monday night Iowa caucuses were released, showing the former South Bend, Ind., mayor leading the field.

The first batch of results, accounting for 62 percent of the approximately 1,700 precincts across the state, showed Buttigieg leading with 26.9 percent of the delegates. Sen.

Buttigieg, however, could face a tougher challenge in more diverse states. He has failed to gain widespread support from black voters, and polls show him trailing top contenders in South Carolina.

The upcoming Feb. 29 primary in South Carolina will be the first state with a significant portion of black voters to choose a primary candidate.

A spokesperson for Buttigieg was not immediately available for comment.
