States with new poll data since the last update: New Hampshire, Georgia, Florida, Indiana, Texas, Virginia, Washington, New York, Michigan, Missouri, Colorado, Iowa, Mississippi

The Trump deterioration continues. This time in the form of weakening in Missouri:

The range in Missouri results is large in the 1.2 months of polling currently used in the average… from Trump up by 10%, to Clinton up by 1%. But the last four polls before the end of the Republican convention all showed Trump up by more than 5%. The three polls taken after the Republican convention ended have all been worse for Trump.

So Trump’s lead in the poll average drops to 4.8%, and Missouri moves from “Strong Trump” to “Weak Trump”. Trump is still ahead, but it is now close enough that we allow the possibility of Clinton winning Missouri in her “best case”.

Clinton’s best case is now to win 384 to 154, a 230 electoral vote margin. This is the best number Clinton has seen on this metric aside from a two day period in June where Texas looked close for a moment.

Trump may stop sliding in the polls, or maybe even reverse the trend, but we’re not seeing that yet. For the moment, his collapse continues.

82.3 days until polls start to close on election day.
