Since the last update, there was a new Quinnipiac poll in Pennsylvania.

This resulted in status shifts for Biden vs. Trump and O'Rourke vs. Trump.

Biden vs. Trump:

• PA has moved from Weak Biden to Strong Biden
• Trump best case vs Biden has changed: Biden 230 to Trump 308 -> Biden 250 to Trump 288

O'Rourke vs. Trump:

• PA has moved from Weak O'Rourke to Weak Trump
• Tipping point change: Trump by 0.1% in VA -> Trump by 0.5% in FL
• O'Rourke vs Trump expected case changed: O'Rourke 266 to Trump 272 -> O'Rourke 246 to Trump 292

Lets look at some of the relevant charts:

The Quinnipiac poll is the fourth Biden vs. Trump poll in Pennsylvania. The last one, from WPA Intelligence, is looking like an outlier at this point. As with the last post, I will link to a great thread on Twitter by Charles Franklin that explains why this is not entirely unexpected.

The average is currently made up of three polls showing a 7% to 11% Biden lead, one poll showing only a 1% lead, and the 2016 election, which was a 0.7% Republican win. The three polls showing strong Biden leads are enough to pull Pennsylvania back out of the swing state category for now with a 5.6% Biden lead over Trump.

Based on historical Election Graphs average accuracy, this translates into a 93.2% chance of a Biden win.

Meanwhile, this is the third O'Rourke vs. Trump poll in Pennsylvania, and none of them are great for O'Rourke. The best of the three has him ahead by only 1.6%, and the other two have him losing to Trump. Adding in the 2016 and 2012 elections to round out a five poll average, O'Rouke is now behind in Pennsylvania. Trump leads by 0.5%.

Based on historical Election Graphs average accuracy, this translates into a 59.8% chance of a Trump win.

Looking at the comparison view with all of the five best polled Democrats against Trump, you can see that Biden is once again doing better than any of the other Democrats, followed by Sanders, Warren, Harris, and finally O'Rourke.

For those counting, this now puts Biden as doing better than the other Democrats in 9 out of the 13 states where there has been Biden vs. Trump polling. That's 69.2%. Not quite the 83.3% he had a week ago, but still notable.

Looking nationally, the "expected case" where every candidate wins every state where they lead in the Election Graphs average, this now puts O'Rourke in the worst position of these five Democrats against Trump, losing to Trump by 46 electoral votes. Biden does best, winning by 30 electoral votes.

The tipping point also shows O'Rourke doing the worst of these Democrats, with the tipping point being a 0.5% Trump lead in Florida. On this metric though, Sanders does best, leading Trump by 1.0% in Iowa.

In both of these metrics, we have Biden and Sanders very narrowly leading Trump, while Trump very narrowly leads O'Rourke, Warren, and Harris.

But all five races are very narrow. We've got a long way to the election still, and lots of states with little or no polling, but for now, the story is still that this could easily go either way.

537.1 days until polls start to close.
