On Sunday, Republican National Committee Chairman Reince Priebus, also warned Republicans that he expected Biden to perform well on Thursday to help the Democratic ticket regain momentum.

Priebus said that while the gaffe-prone Biden has "of late put his foot in his mouth in very public ways, he was still a "gifted orator." Priebus said Biden is "very good at rhetoric, is very relatable."
