Description

The "blue wall" is a term coined in 2009 in the political culture of the United States to refer to the dozen-or-so states that consistently "voted blue" i.e. for the Democratic Party in the six consecutive presidential elections from 1992 to 2012. This trend suggested a fundamental dominance in presidential politics for the Democratic Party. Conversely, the terms "red wall" and "red sea" are less-commonly used to refer to states that Republicans consistently won in the same timeframe; states which have not voted consistently for one party are called "purple" or swing states.
