This is from a Firehouse poll:

The voters who picked Obama in 2012 and Trump in 2016 in [Pennsylvania, Michigan, and Wisconsin] will likely decide who wins in 2020....In Michigan, 84% of Obama-Trump voters choose Trump regardless of the Democratic opponent. In Pennsylvania, 70-79% support Trump depending on matchup (Biden fares the best, and Beto fares the worst). And even in Wisconsin, roughly two-thirds side with Trump over Democratic opponents.

So 20 months before the election we are all told that 47 states and the District of Columbia will be taken for granted and the pluralities in just three states will decide the next president.  Indeed, not just the voters in that trio but the views only of the tiny fraction of the people in Michigan, Pennsylvania, and Wisconsin who somehow managed to see their way to voting both for Obama and Trump (as opposite in every way is in the two presidents could be) will determine the next president.

This is how the Electoral College system works. How do you like them apples?

This means the preferences, opinions, cares, and needs of 90% of the population are going to be ignored. The wishes of most people don’t matter.  Heck of a system.
