Many political analysts believe Thursday's debate between Vice President Joe Biden and Republican rival Paul Ryan was generally even.
But several have criticized Biden for what they called his disrespectful demeanor.
Fox News anchor Chris Wallace said that as one who had watched presidential debates for decades, "I don't believe I have ever seen a debate in which one participant was as openly disrespectful of another as Joe Biden was to Paul Ryan."
CNN's analysts believed the debate was a draw. But CNN political commentator Gloria Borger noted that Biden "was condescending at times to Paul Ryan."
"I think I could have done with a lot less eye-rolling and chuckling," she said.
Meanwhile, MSNBC's analysts criticized many of Ryan's views, with "Hardball" host Chris Matthews calling the debate a "clear victory" for Biden.
A quick CNN poll after the debate showed 48 percent thought Ryan won, compared to 44 percent for Biden.
