Rasmussen and CNN polls are outliers. The majority of polls show a tighter race, with Trump up by one percent on average nationally. Trump is doing well in Arizona, Nevada, and Georgia, but to get to 270 he has to win one of the three northern battleground states: Wisconsin, Michigan, or Pennsylvania. These are all toss-ups right now.
Real Clear Politics shows Pennsylvania has Trump,on average, 2 points ahead of Biden. That number should be higher but the number got skewed by the March poll done by Marshall & Franklin which showed an outlier Biden plus 10.
