 Joe Biden, who clocks in, according to Fox News, at a maximum of 33 minutes in the majority of the 11 campaign rallies that he's held this year. I think Donald Trump averages 11 campaign rallies in an average month. But Trump, Trump will speak as long as two hours. I watched that Georgia rally, the one after he won the state's Republican primary back in March. I watched the whole thing. Two hours he can talk off the cuff.
