Young Turks host John Iadarola is predicting that the second night of the Democratic presidential primary debates in Detroit will be less “substantive” than the first night and warned viewers to prepare to be “gaslit.”

“I’m going to guess that’s going to be less substantive and it’s going to be focused more on the individual personalities,” Iadarola, who is host of news show “The Damage Report,” told Hill.TV.

“I would say prepare yourself to be gaslit,” he added.

While Iadarola said Tuesday night was dominated by a fierce debate over “Medicare for All” between centrist Democratic contenders and their progressive counterparts, he questioned whether a similar clash would play out Wednesday night among the lineup’s centrist candidates.

“Will it really be a substantive disagreement,” the host on the liberal network said.

The remarks were a shot at Biden's more centrist politics on healthcare. McConnell is the Senate majority leader and has sought to repeal the ACA.

“You might as well FedEx the election to Donald Trump,” Hickenlooper said when arguing why he thought Sanders could not beat Trump.

Biden and Harris are set to take center stage for Wednesday night’s debate, setting up a rematch after the two sparred over Biden’s civil rights record during the first Democratic debate.

Biden has since regained much of his support he lost in the days that followed their high-profile battle and allies have said he will be looking to rebound from his previous lackluster performance.
