The thick blue wall

In an important article in National Journal last month, Brownstein notes that 18 states and the District of Columbia have voted Democratic at least five times in a row, supporting Democrats from Bill Clinton through Barack Obama. Those states — concentrated in the Northeast and the upper Midwest and on the Pacific Coast — provide 248 electoral votes, 29 more than the old Republican lock and more than 90 percent of the electoral college majority…

The states that are part of the blue wall have distinctive characteristics. As Brownstein wrote, they “combine large numbers of well-educated, affluent and less religious whites with substantial numbers of racial and ethnic minorities, including sizable immigrant populations.”
