However, the new Democratic coalition — dominated by upscale whites and racial and ethnic minorities — is badly organized for capturing political power in the federal government. It is heavily concentrated in a handful of states that go comfortably for Democrats, leaving many states to go more narrowly for Republicans.
To wit: Donald Trump lost the popular vote by more than two percentage points in 2016, yet he carried 30 of 50 states and won 304 Electoral College votes.
All in all, the collapse of the Democratic farmer–labor coalition, and the rise of the new upscale–minority coalition, has resulted in Republicans now enjoying a noticeable edge in securing an Electoral College majority, and a huge advantage in winning a Senate majority.
Plurality of the vote matters!!!!
