 It turns out that about 73% of respondents in the Quinnipiac poll say they're going to watch the debate tonight, which means that Joe Biden needs a strong showing. He particularly needs a strong showing because there is a Times-Siena poll out that shows that Joe Biden is also down four points. Right now, he is down 48-44. That is the biggest lead that Donald Trump has had in the National Times-Siena poll among likely voters in months.
