I believe Rasmussen polls are biased towards GOP. It’s probably closer to 49-45.
There are polls on both sides which slightly favor each side, which is why it is important to look at the average of ALL polls.
When all the dust clears and polls from both sides and the middle are factored in by next week the numbers will most likely show the race right where it was with Biden as the nominee with Trump ahead by 2-3 points nationally and ahead in all or nearly all of the battleground states.
