Biden was up about 8 nationally and given Trump's increasingly insane behavior of late, his calamitous debate performance, and the fact that he probably had COVID but didn't tell anyone during the debate - the 14 point lead seems legit. If its real then that's about a 400 electoral vote result for Biden on November 3rd (Obama beat Romney by 6% nationally, which was good enough for a 332 to 206 electoral college win).
You understand they over sampled Dems by 15%... Yea real accurate ...
