Joe Biden is ahead of Trump in all the swing states.
What ever Joe Biden is doing, he should do more of it.
To add to your point.
We have 31 states in the safe zone. Biden is safe in Hawaii, Washington, Oregon, California, Illinois, Maryland, Delaware, Washington D.C, New York, New Jersey, Connecticut, Mass, Vermont, Rhode Island, and 1 district in Maine. That comes to 14 contests for a total of 183 electoral college votes. Trump on the other hand is safe in Alaska, Idaho, Montana, Wyoming, Kansas, Oklahoma, North Dakota, South Dakota, Arkansas, Nebraska (4 out of the 5 electoral college votes), Arkansas, Mississippi, Alabama, Tennessee, Kentucky, West Virginia, and Indiana. That comes to 17 contests for a total of 100 electoral college votes. Keep in mind these are all the states RCP marks as non-toss-up states and there are no polling data showing Trump/Biden leading in single digits.
This leaves 20 states up for grabs. Biden is currently leading in 14 out of the 20. Virginia, Colorado, and Maine are moving more and more into the safe zone, but I am being ultra-conservative with my estimates.
