YouGov MRP Model Forecast
(This is the type of forecast which has been most accurate in the UK in the last few elections).
We estimate that Biden will win the national popular vote by 9% with a margin of error of +/- 3.2%. Our state level estimates are shown in the table below. Biden is leading in 28 states with 350 electoral votes and Trump is leading in 20 states with 126 electoral votes. In the remaining 3 states (with 62 electoral votes), Biden and Trump are within 2% of each other. Our best estimate for the electoral college is that Biden will win 382 electoral votes with a 95% confidence interval ranging from 314 to 412 electoral votes.
The cruical big call on this is Texas going blue. Which would be HUGE. It also has Florida and North Carolina going blue.
This doesn't take into account any dodgy doing with voter suppression though, so I'm inclined to take a huge pinch of salt with this.
