READ HERE: President Joe Biden opened the debate with a raspy voice and disjointed, rambling answers, reigniting Democratic concerns about his age and ability to take on former President Donald Trump.

Many of the president’s answers were hard to follow. At one point, seemingly losing his train of thought, Biden said “we finally beat Medicare,” misspeaking about his own policy on earned benefits.

In text messages with POLITICO, Democrats expressed confusion and concern as they watched the first minutes of the event. One former Biden White House and campaign aide called it “terrible,” adding that they have had to ask themselves over and over “What did he just say? This is crazy.”

Another veteran Democratic operative texted, “Biden seems to have needed a few minutes to warm up. I wonder if the lack of an audience was the right decision. And poor guy needs a tea. Maybe a whiskey.”

Jay Surdukowski, an attorney and Democratic activist from New Hampshire who co-chaired Martin O’Malley’s 2016 presidential campaign in the state, said, “Biden is toast — calling it now.”
