Helmut Norpoth predicts that Trump will win the 2020 election in a landslide victory. Careful consideration of each singular state, as well as the primaries, lends a better understanding of how votes will be distributed via the electoral college.
The Helmut Norpoth model has correctly predicted 24/26 elections, the only two missed being JFK and Bush 2000, both of very slim margins.
HN correctly predicted the 2016 election, unlike polls performed by other agencies. Polls are not scientific models.
While states such as California and Illinois (and even Michigan if you lend Biden a few more states) carry a massive number of votes, but thanks to the electoral college, California and Chicago will not dictate who wins the election in 2020.
This is why polls are not effective, as they rely on opinions and responses from the general population. Those are not scientific in the least.
The HN model uses scientific data and primary performance, and it’s not even going to be a close one according to the study.
