Washington Free Beacon editor in chief Matthew Continetti said 2020 Democratic hopefuls support policies such as expanding the Supreme Court and abolishing the Electoral College because they believe they cannot pass progressive policies unless they "change the structure" of the Constitution.

Continetti's comment came during a Tuesday discussion on Fox News Channel's Special Report about why proposals concerning the structure of U.S. government have gained support among Democrats.

"The Democratic argument isn't with any single one of these things: it's not only with the Electoral College, it's not only with the 26th Amendment, it's not only with the state of the Supreme Court, it's not only with equal representation of small states in the United States Senate," Continetti said. "The Democratic argument is with the Constitution of the United States of America. The argument is because the left cannot win its arguments when they present them publicly, and in order to win, they need to change the structure."

Continetti went on to reference 2020 hopeful Pete Buttigieg, the Democratic mayor of South Bend, Indiana, who said when it comes to the Supreme Court, "structural change is necessary."

"If we want to save that institution, I think we better be ready to tune it up as well," Buttigieg said while speaking at Saint Anselm College last week. 2020 candidate Beto O'Rourke has also discussed the issue, saying at a rally last week that he thinks expanding the Court is "an idea we should discuss."

In addition to discussions about packing the Court and abolishing the Electoral College, some Democrats—including Speaker Nancy Pelosi (Calif.)—have expressed support for lowering the minimum age requirement for voting to 16.

Sen. Elizabeth Warren (D., Mass.) came out in favor of abolishing the Electoral College during a CNN Town Hall on Monday night, saying, "We need to make sure that every vote counts."

"[T]here’s a lot of wisdom in" the idea, O'Rourke agreed the next day.

Continetti said these measures are antithetical to the basic structure of the United States.

"They are changing the Constitution of the United States, whose structure is there to preserve individual liberty," Continetti said. "Barack Obama said he was audacious—this is audacity."
