WATCH: Jon Stewart Rips Into Demands to 'Get on Board' With Joe Biden

Jon Stewart spent a segment on his Monday show railing against calls to fall in line behind Joe Biden's candidacy. 

Long before the first Presidential debate, Jon Stewart was raising questions about Biden's age and his ability to serve another term in office. The President's debate performance did nothing to quell Stewart's concerns. 

The Daily Show host spoke about demands from the White House and some in the media that people move on from worries about Biden's age. Stewart wasn't having it at all. 

Stewart opined that the debate was a "shocking display of cognitive difficulty — recognizable to, unfortunately, anybody who's dealt with aging parents. And it's a hard watch."

The host continued, "We expect him (Trump) to be f----ing crazy. But Biden's performance and inability to articulate at times was stunning. Like, I could not believe what I was watching."

The comedian closed his message, "An arthritic status quo, unable or unwilling to respond in any way to the concerns of voters, who just received new and urgent information about their candidate, also erodes confidence and faith in the system of government. Get on board or shut the f--- up is not ... a particularly compelling pro-democracy bumper sticker."
