They aren't, you clown, YOU are the one saying that.
FFS, you dorks are on here pretending Biden "curbstomped" Trump in the last debates, and none of you have posted a single clip or segment, not not quotes, or even a paraphrase of where you think Biden "owned" anything, you just claim it with nothing to support it. The most notable thing that happened in the last debate was Joe getting called out for his family's corruption, claiming nobody in his family ever made a penny in China, and claimed the laptop full of emails detailing their corruption was "Russian disinformation", both of which have been proven to be lies, and Kristen Welker cutting off the conversation to save him and say "ok, I want to get back to calling you a racist".
Not even democrats thought Biden "won" anything at the time, they all said the moderator "won" the debate, and there would obviously be a million videos of all these instances of Biden "owning" Trump if they existed anywhere, but you can't because everything Biden said has been proven to be lies already.
Political pundits noted the calmer and less chaotic scene than in the first Trump-Biden showdown in Cleveland
